This does relate to tyres so it is in the right section

Think I have found the ideal tyre dimensions but am hoping you are all going to say the speedo takes its' reading from the rear. Take a looky and you will see what I mean

It takes the speed from the gearbox

10 out of 10 for trying mate but your tyre size will still vary your speed so choose your r/c with care

By using larger wheels say 16's to 18's you are messing with the overall gearing of the cars set up. If you use a higher size rim then the chances are you would gain on acceleration and loose top end in theory. I can only quote from using different sized sprockets on a motorbike. So I might be wrong

change them then recalibrate your clocks.....

Take care when deciding what size you need on a GTT as the traction control is very fussy.

If the overall size goes up, acceleration goes down but top speed increases (assuming you have the power).

Smaller wheels/tyres means better acceleration but lower top speed. :sorry:

I should have stuck with my R33. Nothing is straight forward with R34s :disappointed:

Was going to go with Rota GTRs

Front
18 x 8.5 with a 235x35 tyre
Rear
18 x 9.5 with a 255x35 tyre

Saw these on a car at yours Richard so was kinda hoping they would be okay. Unless the chap just drives with tcs turned off


ps. Forget I even asked where the speedo was taking its reading. Dumb ass question :slap:
