Hi I have been searching non stop on the IS 2Gn site but thought I would post a question here...

I am really enjoying my new IS350 AWD but I want to upgrade to 18s or 19s wheels with a lowered ride height of 1" with f-sport springs.

My question is what is the advantages/disadvantages of going wider all around and Is there a point after which tire width will hinder performance??

Stock is 225/45/17 I am thinking of going 235 or 245. Would I be better to stick with OEM width of 225 for the AWD and just change the side wall height to compensate for the larger diameter rims?

Thanks, any opinions comments especially from people that have a non-staggered set-up on the AWD would be appreciated

All else being the same, a wider tire will have better handling grip, and dry acceleration, if you are capable of breaking the tires loose that are on there... wider tire also means a little more rolling resistance which can decrease fuel mileage (but so will larger diameter wheels), and not as good hydroplaning or snow performance...

those things being said, it is very popular to go with a 235/40-18 or a 235/35-19 on your car... these sizes will be slightly wider, yet retain very close to the OE tire diameter, which keeps the speedo and odometer in check...
