R’ stands for radial, which is the most common type for commercial truck tires. This is the diameter of the wheel rim in inches that the tire is designed to fit.Decoding Tire Sidewall Numbers P: Tire type (P stands for passenger vehicle) 215: Tire width in millimeters from sidewall to sidewall.

Rim diameter and rim type. Rims with .According to various manufacturers’ load and inflation tables, a typical standard-profile 11R22. LRG tire needs 105 psi to get beyond 12,000 pounds load carrying capacity. For example, Michelin’s tables indicate a pair of such tires would be good for 12,350 pounds (6,175 pounds each). E-rated tires are perfect for wheels handling heavy loads daily. They ensure the durability, controllability, and performance of the vehicle. Table of Contents: What Does Load Range Mean?C and D load range tires are the most used when it comes to medium to larger-size trailers, but if you’re hauling a heavy-duty trailer, load range E tires are probably what you need.Load Range E indicates a specific tire’s load range rating. They are also known as 10-ply tires. These tires are capable of handling 1,520 lbs at 80 psi. Ply rating E tires for trailers are capable of safely performing under their maximum load-carrying capacity of 1,520 lbs per tire.Both will have an aspect ratio of 88%, so the sidewall height of the 10R22. R22. The 295/75R22. R22.Performance: 33 vs. Visual Effect: 35-inch tires create road presence with their bolder looks while the 33s provide a more muscular yet slightly milder stance.If you run them low as some people do you are asking for a sidewall blowout. Over 4 million miles driving a truck running either 11r22. While you should always stay within this range, you should also never be below 20 PSI, or over 50 PSI, or you risk serious tire damage (more so than with standard overinflated or underinflated tires to a lesser degree).Pressures below 20 PSI are considered “flat” and dangerous to drive on. Usually, low pressures indicate a puncture but can also occur over long periods naturally as air escapes.
Is 40 PSI too high for truck tires?
In most of these cases, 40 psi should be more than enough, and since most modern tire designs will allow up to 44 psi (in some cases more) this is not a problem. If you have a heavily loaded vehicle, up to 44 or even higher is ok if the tire allows it, but this is a little high for most vehicles. I’ve spoken to a few mechanics and they tell me operating in the 35-38 range s fine and will also extend the life of the tyre a little. Running up in the 40s will shorten the tyre life. Im assuming his psi goes up to around 40/44 during driving simce he said he is on summer weather.In most of these cases, 40 psi should be more than enough, and since most modern tire designs will allow up to 44 psi (in some cases more) this is not a problem. If you have a heavily loaded vehicle, up to 44 or even higher is ok if the tire allows it, but this is a little high for most vehicles.You can safely over-inflate tires by up to 10%. For example, if your tires have a recommended PSI of 35, you can go up to around 38 PSI without worry. Anything more than that is too much and not recommended.
