Wheel and tire sizes....what is too much?

[spannermanager]

Good point Steve, and Theoretically yes, but the the other advantages outweigh it, temperature gain as above, is better than a cold but wider tyre, and you can go to a very wide tyre and wheel to gain back footprint without being absurdly heavy, very fast heating of the tyre and the brakes/ hubs/ tyre core from faster rotation, I lost traction with them at first, but gained it back mostly with tyre pressure experience and launch techniques, it was just adjusting to something different, I'm amazed at how quick minis launch on 10" wheels, tho many run 11" wide tyres, again, to get footprint area. Gearing is my problem on the circuits, the cure I want is a berg 5 speed 091.. Not much really then...
