Contact Drag Racing Rear 45mm Wide Tires (30 Shore)
I’ve got three different Traxxas 4-Tec 2.0/3.0 touring cars, each with a different wheelbase. Two of the cars have solid-steel differentials, which causes tire wear on corners. Regardless, every car is highly modified for speed.

That being said, I LOVE Contact tires!

I prefer 25 Shore for my purposes (on the asphalt surfaces being used for testing), but 30 Shore also works well for me on warmer asphalt surfaces.

I use 32mm front and 45mm rear, and I drive the living daylights out of the cars, and tire wear is minimal. Yes, it leaves burnout marks all over the pavement, but THE TIRES DO LAST A LONG WHILE, and are reasonably priced; I love them and have multiple purchases.

Side note: there may be a speed limit…after running 70 MPH a few times, I found a large crack in one of the rear tires, and there were no crash issues.

I’m thinking this crack was created from excessive centrifugal force due to excessive RPMs; the plastic composite stretched beyond its limits.

The car’s final drive gear ratio is 5.692 to 1, with a 3850 Kv motor running a 3S 8000mAh 100C battery, and the wheel OD is 69.5mm.

So, with the 3S battery at top voltage of 12.4vDC, the motor’s top RPM is 47,740, giving us 8,387 RPM at the tire. This may be the problem.

But, I digress. ROFL.

Thanks for your time on this matter.

Peace!
