Hi all,
Am new here too. Will pickup my new 08 IS250 Sports Luxury in a few weeks - I hate the wheels on it (couldn't beat the salesman down to add the 18" 'X' wheels at a reasonable price - he wanted $A3,000 for them!!!), so am going to get some 18x8s aftermarket. Have already spotted a set at Tempe Tyres & they're offering me the new mags + 4 Kumho 245/40 x 18 Ecsta SPT KU31's as a package for $1400 (less trade on the old 17" wheels). What I'm after is any info on the actual tyre sizes I can fit to my new car. The sales brochure specs show that the Sports Luxury has 225/45 x17 x8.0" front & 245/45 x 17 x8.0" rear while the Sports has 225/40 x18 x8.0" front & 255/40 x18 x8.5" rear – thus they both seem to have the smaller width 225 tyres on the front, even though they both use 8” wide rims on the front. I asked the dealer about this & he said "(he) personally would not fit a 245/40r18 to the front for the simple fact they are a very wide tyre and not worth the trouble they could cause on the front, by scrubbing on the guard under cornering and load".
I'd like to fit 245/40 x18s (on 8.0" rims) all round but am obviously concerned that I'll stuff up the front with scrubbing etc. Does anyone have any thoughts / experiences to share on this so I can try to take a view on whether to go with 225s or 245s on the front? Also, if anyone has any views on Kumho's I'd be interested too as I've never used them before - a mate has some on his Monaro & he's happy with them.
Cheers...Thx for any input here.
