I have watched with interest when you fella’s fit oversize wheels and tyres, and the result Is always an improvement on the original. They fill the arches and look good.
But one thing puzzles me, what do you do, to compensate for the extra rolling diameter?
The speedo must be out, and, to some extent the gearing, and if the wheel is quite a lot larger, The acceleration must be ruined.
Do you re-calibrate the speedo, or use a satellite driven one?
Do you change the gearbox ratios or back axle?
The most extreme example I can think of recently was Patoune on his D Type, he fitted 185 x 100 x 13 tyres, which would result in a whopping 21 % + increase in rolling diameter.
The acceleration must have been snail-like in the extreme!
No pun intended!
I understand he races them, so I guess he must have swapped the gearbox or back axle, or both.
If you’re reading this Patoune, please, what mods did you make, I’m really interested?
