Evening all, long time since I've been around these parts, but here I am again asking questions.
My IS200's OEM 17" wheels are looking increasingly pitted and...well...crap, so I'm mulling over putting winter tyres on them and buying a new set for summer use. I'm not looking to increase to 18's or anything like that since the roads over here are bumpy enough on 17's. That said, I've seen some conflicting stuff online about what offsets I can use on 17" wheels. I know OEM is +50 and 7" wide, but I've seen at least one website claiming that 7.5" width with 40 offset will work. Any thoughts on this? It seems counter to Monster Mat's excellent table above. My car is not lowered, and if anything seems to ride a little higher than stock, especially at the rears.
To be honest, I'm a bit bamboozled by all of this, since in my mind a lower offset means I'm less likely to foul the struts, no? In my car at least, there's no danger of rubbing the arches.
Thanks for any advice.
