Wheel Size Question.

interesting about deciding I want to run a 275mm tire...The suspension dictates the tire. You are going to build the car to that tires capability ? You don't even know what the capability of it is because you haven't run it yet. Just an FYI tread wear ratings are different between all manufacturers and even within the same manufacturer different tire lines. There is NO industry standard on Tread Wear ratings. It was supposed to be that way but to do so would mean that some one like the DOT would have to establish a standard. All manufacturers would have to agree to the same standard and then someone would have to pay to monitor and enforce the standard. Never happen.
The tread wear rating is established by the tire company as a standard of measure between THEIR own tires. So a 200 twr by Michelin would not be the same as a 200 by Goodyear or Hankook, Pirelli, Dunlop.....And it also is no indictor of the actual traction of the tire. Low tread wear numbers just mean the tire wears faster than a higher tread wear rating of that manufacturer. Not a measure of traction. That is partially addressed by the traction letter codes A, AA, AAA but again not an industry standard. And under what conditions? Tire size, load being carried by the tire, remaining tread depth, speed of the tire, air pressure in the tire, wet or dry, surface, asphalt, concrete, dirt .... The package determines the tire not the other way around, except if you just like a tire and make the car fit it I guess. Not really efficient.
