Here is a picture of a 17/17 setup, from the german site. (fronts look too big, but the rear looks great imo
In total there is nearly 10kg of unsprung weight to be lost using these over TBs and 20kg over speedlines.

Not like it would make much difference whether it was unsprung or sprung on some of the VX's with their ridiculous suspension setups

I've looked and Bridgestone have removed the data for RE040, so can't get the width data. But a quick calculation came out at having ET20 for the 8,5J wheel
A more sensible compromise is the 235/40/17, tw=216*, sw=238* , which will go on a 8J rim.
given the difficulties a number of us have experienced getting tyres fitted to a 7.5J , this is one of the reasons why I prefer 8J minimum
I've avoided going to larger wheels sizes to the bad effects on the wishbone angles and CV joints and the need to change suspension setups. If I was to change, I'd go to 15" all round, like Meldert did.
*sizes given from manufacturer data for Federal RS-R
tyre weights if anyones interested in total USM , plus actual sizes versus nominal sizes
RS-R , 6.5mm tread depth (http://www.federalti...c/spec595RS.pdf)
225/45/17 = 11.2kg , tw=206, sw=230
235/40/17 = 11.5kg , tw=216, sw=238
255/40/17 = 12.4kg , tw=232, sw=260 (8.5J)
R888 , 5mm tread depth (http://www.racetire....s/toyo_r888.htm)
225/45/17 = 10.9kg , tw=221, sw=231
235/40/17 = 10.9kg , tw=238, sw=243
245/40/17 = 11.4kg , tw=238, sw=249
255/40/17 = 11.8kg , tw=259, sw=264 (8.5J)
315/35/17 = 13.6kg , tw=300, sw=320 (the MaxR super wide option! , 11J rim needed)

Problem with that is the availability of wide affordable 15" tyres is not good. In my view if we are increasing the rear tyres to 235 or 245 (10 and 20mm respectively) then it makes sense to go 205 or 215 on the front to keep things balanced. There is some very keen pricing on 17" 215 & 245 tyres (cheaper than 16" 195 & 17" 225) so it just makes sense to me to go 17" all round.

Thanks Alanoo!


These have spacers and longer bolts which is why a new cast is required (and the point of this thread)
