If Kenny Brown or anyone in the motorsports world is telling people - especially Mustang drivers! - that they can have "too much tire" width, well then he has lost even more relevence in this industry than I had thought.
JJ I know he is your hero and that his jacking rails give YOU two seconds a lap, but for the rest of us - THE TIME CLOCKS DON'T LIE.
I can easily bury Kenny or JJ or anyone else selling those "small tires are better" nonsense with real data, results, and lap times. When we started competing in our S197 in 2010 we were on little 265mm tires, due to class limits.
Going to an inch wider wheel and tire, the car got faster and easier to drive. Tires lasted longer, too.
As we went to 18x11 then 18x12" wheels and 315mm tires... guess what? The car got faster and easier to drive, and tires lasted longer. Braking was not effected.
With 335 and 345 tires, wanna guess what happened? The car got faster and easier to drive, and tires lasted longer!
Car after car, class after class, lap record after record, wins and more wins... wider tires LOWER LAP TIMES and INCREASE TIRE LIFE. It is not an opinion. It is not "theory". It is factual and I have thousands upon thousands of data logged laps to prove it. At all power levels. With and without aero. Street tires and R-compounds. WIDER IS ALWAYS BETTER.
If there is a tire width where cars
start to slow down, in autocross or track use, we haven't found it yet. And we've tried!
STOP LISTENING TO KENNY BROWN - HE HASN'T RACED ANYTHING OR POSTED ANY REAL DATA IN AGES. He sells trinkets and doo-dads, and nobody should listen to his tire advice. I am not allowing people like JJ to muddle this forum with more of his nonsense. WE AREN'T BUYING WHAT HE'S SELLING!
