The codes do not go beyond 150mm in width. With these tires, the first number of the tire size is not the actual width, it is just a number. The M-code is what tells you the actual width. | Scooters | 10" diameter wheels (scooters) | 1 oz | 12" & Up diameter wheels (scooters) | 2 oz | Dual Purpose / Off Road with Rim Locks | Front - 80 - 120 mm tire width | 2 oz | Rear - 130 -230 mm width | 3 oz | Rim Locks - add one ounce over what you normaly use for that size tire to accomodate the additional weight of the rim lock. Two rim locks opposite each other don't require any more Dyna Beads other than stated above, as they have a tendency to cancel each other out. | Note: Filtered valve cores do not fit all stems. They require a seat 1-1/4" down in the stem. If you cannot use them, simply rotate the tire so the valve stem is about the 6:00 position, then give the valve stem a quick shot of air prior to checking pressure. | | | | Commercial / Large Truck | Tire Size | Single Wheel | Dual Wheel | | Tire Size | Single Wheel | Dual Wheel | | 7.00 R15 | 3 oz | 3 oz | | 7. 50 R20 | 8 oz | 10 oz | | 7.50 R15 | 6 oz | 6 oz | | 8.25 R20 | 8 oz | 10 oz | | 8.25 R15 | 6 oz | 6 oz | | 9.00 R20 | 10 oz | 12 oz | | 9.00 R15 | 8 oz | 8 oz | | 10. 00 R20 | 10 oz | 12 oz | | 10.00 R15 | 8 oz | 8 oz | | 11.00 R20 | 12 oz | 14 oz | | 1000 R15 | 8 oz | 8 oz | | 1000 R20 | 12 oz | 14 oz | | | | | | 12.00 R20 | 14 oz | 16 oz | | 195/65 R16 | 4 oz | 4 oz | | 1200 R20 | 14 oz | 14 oz | | 245/65 R16 | 4 oz | 4 oz | | 12. 50 R20 | 14 oz | 16 oz | | 305/65 R16 | 4 oz | 4 oz | | 13/80 R20 | 12 oz | 12 oz | | 205/75 R16 | 4 oz | 4 oz | | 14/80 R20 | 12 oz | | | 225/75 R16 | 4 oz | 4 oz | | 14.00 R20 | 16 oz | | | 245/75 R16 | 4 oz | 4 oz | | 16. 00 R20 | 16 oz | | | 265/75 R16 | 4 oz | 4 oz | | 275/80 R20 | 12 oz | 14 oz | | 285/75 R16 | 5 oz | 5 oz | | 335/80 R20 | 12 oz | 14 oz | | 315/75 R16 | 5 oz | 5 oz | | 365/80 R20 | 12 oz | | | 215/85 R16 | 4 oz | 4 oz | | | | | | 225/85 R16 | 5 oz | 5 oz | | 10 R22 | 12 oz | 14 oz | | 235/85 R16 | 5 oz | 5 oz | | 11 R22 | 12 oz | 14 oz | | 245/85 R16 | 5 oz | 5 oz | | | | | | 255/85 R16 | 5 oz | 5 oz | | 8 R22. 5 | 8 oz | 10 oz | | 265/85 R16 | 5 oz | 5 oz | | 9 R22.5 | 8 oz | 10 oz | | 275/85 R16 | 5 oz | 5 oz | | 10 R22.5 | 8 oz | 10 oz | | 345/65 R16 | 5 oz | 5 oz | | 11 R22. 5 | 10 oz | 12 oz | | 7.50 R16 | 4 oz | 4 oz | | 12 R22.5 | 12 oz | 14 oz | | 8.25 R16 | 6 oz | 6 oz | | 13 R22.5 | 14 oz | 16 oz | | 9.00 R16 | 6 oz | 6 oz | | 15 R22. 5 | 12 oz | | | 11.00 R16 | 10 oz | 10 oz | | 16.5 R22.5 | 14 oz | | | | | | | 18 R22.5 | 16 oz | | | 265/70 R17 | 6 oz | 6 oz | | 275/50 R22.5 | 10 oz | 12 oz | | 275/70 R17 | 6 oz | 6 oz | | 385/65 R22. 5 | 14 oz | | | 285/70 R17 | 6 oz | 6 oz | | 425/65 R22.5 | 16 oz | | | 305/70 R17 | 6 oz | 6 oz | | 445/65 R22.5 | 18 oz | | | | | | | 11/70 R22.5 | 10 oz | 12 oz | | | | | | 235/70 R22. 5 | 10 oz | 12 oz | | 8 R17.5 | 5 oz | 6 oz | | 255/70 R22.5 | 10 oz | 12 oz | | 8.5 R17.5 | 5 oz | 6 oz | | 265/70 R22.5 | 10 oz | 12 oz | | 9 R17.5 | 6 oz | 6 oz | | 275/70 R22. 5 | 10 oz | 12 oz | | 9.5 R17.5 | 8 oz | 8 oz | | 305/70 R22.5 | 10 oz | 12 oz | | 10 R17.5 | 8 oz | 8 oz | | 315/70 R22.5 | 10 oz | 12 oz | | 11 R17.5 | 8 oz | 8 oz | | 245/75 R22. 5 | 10 oz | 12 oz | | | | | | 265/75 R22.5 | 10 oz | 12 oz | | 195/70 R17.5 | 5 oz | 6 oz | | 285/75 R22.5 | 10 oz | 12 oz | | 215/70 R17.5 | 5 oz | 6 oz | | 295/75 R22.5 | 10 oz | 12 oz | 235/70 R17. 5 | 5 oz | 6 oz | | 315/75 R22.5 | 10 oz | | | 245/70 R17.5 | 5 oz | 6 oz | | 345/75 R22.5 | 12 oz | | | 265/70 R17.5 | 5 oz | 6 oz | | 350/75 R22.5 | 14 oz | | | 205/75 R17.5 | 5 oz | 6 oz | | 235/80 R22. 5 | 10 oz | 12 oz | | 215/75 R17.5 | 5 oz | 6 oz | | 255/80 R22.5 | 10 oz | 12 oz | | 225/75 R17.5 | 6 oz | 8 oz | | 275/80 R22.5 | 10 oz | 12 oz | | 235/75 R17.5 | 6 oz | 8 oz | | 295/80 R22. 5 | 12 oz | 12 oz | | 205/80 R17.5 | 5 oz | 6 oz | | 315/80 R22.5 | 12 oz | | | 225/80 R17.5 | 5 oz | 6 oz | | 365/80 R22.5 | 12 oz | | | 225/90 R17.5 | 6 oz | 8 oz | | | | | | | | | | New Michelin XDA2+ Energy | 7. 50 R18 | 8 oz | 8 oz | | 315/80 R22.5 | 12 oz | | | 8 R19.5 | 6 oz | 8 oz | | 295/80 R22.5 | 12 oz | | | 9 R19.5 | 6 oz | 8 oz | | 315/70 R22.5 | 12 oz | | | 18 R19.5 | 14 oz | | | 305/70 R22. 5 | 12 oz | | | 225/70 R19.5 | 6 oz | 8 oz | | 275/70 R22.5 | 10 oz | 12 oz | | 245/70 R19.5 | 8 oz | 10 oz | | 315/60 R22.5 | 12 oz | | | 265/70 R19.5 | 8 oz | 10 oz | | 295/60 R22.5 | 10 oz | 12 oz | 275/70 R19. 5 | 8 oz | 10 oz | | | | | | 285/70 R19.5 | 8 oz | 10 oz | | | | | | 305/70 R19.5 | 10 oz | 12 oz | | | | | | 280/75 R19.5 | 8 oz | 10 oz | | 11 R24 | 12 oz | 14 oz | 385/65 R19. 5 | 14 oz | | | 12 R24 | 14 oz | | | 425/44 R19.5 | 14 oz | | | 14 R24 | 16 oz | | | 435/50 R19.5 | 10 oz | | | | | | | 445/45 R19.5 | 12 oz | | | 11 R24.5 | 10 oz | 12 oz | | | | | | 12 R24. 5 | 12 oz | 14 oz | | | | | | 285/75 R24.5 | 10 oz | 12 oz | | | | | | 305/75 R24.5 | 10 oz | 12 oz | | | | | | 315/75 R24.5 | 10 oz | 12 oz | | | | | | 275/80 R24. 5 | 10 oz | 12 oz | | | | | | 295/80 R24.5 | 10 oz | 12 oz | | | | | | | | | Super Singles | | 445/50 R22.5 | Michelin X One XDA/XTE/XRV/XTA | 14 oz | | 445/50 R22.5 | Michelin X One XDA-HT Plus | 16 oz | 445/55 R22. 5 | Michelin X One XDA-HT Plus | 16 oz | | 445/50 R22.5 | Bridgestone Greatec Drive | 16 oz | | 445/50 R22.5 | Bridgestone Greatec Trailer | 14 oz | | 385/65 R22.5 J | GoodYear G286A | 14 oz | | 425/65 R22.5 L | GoodYear G286A | 16 oz | | 445/65 R22.5 L | GoodYear G286A | 20 oz |

Wheel width, tire profile height. Tire index tables.
For example: you have a 175/70 R13 wheel on your car. Using this table, we determine the profile height of your tire 175 by 70, we get 12.
2 cm. If you want to put the tire wider and leave the wheel height the same, then select a value close to 12.2 from the table.
We get the size 205/60 R13. If you want to increase the size of the disk, leaving the wheel height the same, the following calculations are necessary: 175/70 R13 the profile of this wheel according to the table is 12.2 cm, multiply it by 2 because. wheel height consists of two profile values 12.2x2=24.4 cm. Next, add the size of the disc, R13 is 13 inches, convert to cm. 13x2.54=33cm. Then add the two values 24.4+33=57.4cm. this is the full height of the wheel. Now, having done some simple calculations, you will understand that you can put 195/50 R15 or 185/60 R14, for these sizes, the wheel height is about the same - 57cm. But we should not forget that with an increase in the width of the tire, it is desirable to increase the width of the disk. Usually, the standard wheel height on the machine can be increased by 1, maximum 2 sizes. Before you change the dimension of the wheel, you can always consult with our highly experienced specialists.
In some cases, the car has regular wheels of the same radius, but different widths, and the height of the wheels must be the same. (BMW 7 SERIES front 235/50 R 18, rear 255/45 R18). For all these calculations, this table was created.

Car and truck tire load and speed index tables
Main Page→→
Tire Speed Index
The tire speed index, which has a letter designation, shows the maximum allowable tire speed.
At the same time, manufacturers emphasize that for safety it is necessary to maintain a speed 10-15% lower than that indicated in the tire speed index. Minor speeding is only allowed for short periods, such as when overtaking. If the speed index is exceeded constantly, then the probability of tire destruction is high. Therefore, it is so necessary to familiarize yourself with the tire index table before buying and, based on your driving style, choose tires. In addition, many manufacturers produce the same tires with different tire speed indexes. Of course, the cost of such passenger tires is directly proportional to the permissible speed.
It is worth dispelling the myth that a high speed index is a consequence of a higher tire mass. In fact, if in some cases this is observed, then it is so minimal that it will not affect the operation of the suspension in any way. And in order to correctly calculate the maximum weight per wheel, you should familiarize yourself with the tire load index table.
Tire load index
The tire load index is an important parameter showing the maximum weight that falls on one wheel of the car. This parameter is especially important for those who often load their car and, especially, for truck tires. Here we must immediately make a reservation that it is necessary to determine the tire load only using the load index table. Some motorists believe that it is possible to divide the mass of the car by the number of wheels - in fact, it will not be possible to accurately calculate the load index in this way, since the weight of the car is far from always evenly distributed between the axles. Sometimes the weight of the vehicle is approximately equal to the sum of the loads on the tires. In such a case, the load index is considered in conjunction with the speed index.
The load index is not a strict parameter and an excess of 20-30% is acceptable in some cases. It is quite another matter to constantly exceed the load index, which can lead to a hernia or tire rupture.
When studying the tire load table, do not forget that a high index indicates that the tire carcass is rather thick, the rubber is dense, which means you should not count on a comfortable ride, since such tires have less bump absorption.
