If you search the net there are programs that calculate the rolling radious of wheel\tyre combinations

Heres one for comparing 2 different sizes at a time. Its about half way down the page.

17" wheels are heavy. If you need them to get the right gearing it is better to get a lower ratio diff. The extra cost of the diff will be offset by the cheaper smaller rims and tyres and the improved handling due to the lower unsprung weight.

Bling is for people with no taste!

The size of the viento means it realy suits 17 inch...

Smaller sizes make the body look out of prportion...

Anyone suggest what brand of tyre to go for ..

toyo proxes r888. i love mine

they are amazing, but soft and sticky to the point where they pick up bits of paper in car parks and stuff at the end of a run.
a bugger for flicking gravel too, but you can forgive them all that.

go with 17s, they look loads better on a glass fibre body. 13s are for locosts.

for all the argument about weight, 17" pro race 1s with tyres are lighter than the mirage wheels in 15" and a load lighter than voodoos in any size. so if weight's all that's in it, i'm a damn sight better off than most.

i am aware of the effect of lower aspect ratio and stiffer sidewalls, just before the barrage of flack

I go for the smaller wheel, slightly higher sidewall thing as it does tend to make the car a lot more forgiving on the limit and makes slides much more progressive. Also 13" wheels are nice and light.

I am using 15" wheels but only cos I already had them. If I didn't then it'd be 13" wheels. Those Ford 13" RS mag wheels are great, cheap as chips and about as light as you can get unless you go for billet centres and split rims.

I have 235/40/17 Rears and 205/45/17 Fronts on my Indy. Look fantastic, but are awful on track - hence my 15" Dunlop Steels and slicks.

Who cares what your wheels look like when people can only see the back of you?

I was planning 235/40/17 on rear and 205/40/17 on front.

Thanks
