Does everybody have to run small wimpy tires?
You know, I actually ran a new set of tires for our Tire Sponsor (OTR WHEEL ENGINEERING)
These were 27/9/14... They worked perfectly too... but I would have preferred to run some 25" tires myself.
The smaller the tire the more control you have of the car... AND, the less rotating weight too.
We have tried everything... You couldn't get the Bounce out of the 28s. 27s seem to be a great medium because you still have some height for the when the deeper ruts show up.
We have settled on 26" for our main tire choice tho... Less weight, and less sidewall to cut, and the car really feels planted too!
My boy actually ran some 26 OTR wizzards with no air, just tire blocks in them.
I do not recommend this now either. After lap 2, he had almost a minute lead over 3rd and right on the leader's tail. Well, his rear tires developed flat spots and started shaking the car badly. Especially in the faster sections. He thought the rear radius rods or bearings was coming apart, so he slowed way down... and then a mishap about being in 2wd and not 4wd cost him 2nd place on the last lap too.
