It's offset that dictates that.

Any reason you want 18s?

18x9 all round with a +55 or above offset will fit without any arch work.

Interesting, i dont know much about suspension/handling side of things. But i remember M1bjr saying something about running the same size all round was beneficial???

I want 18s to fill the arches, I prefer the look...i've been searching ebay but finding wheel selection hard.

For 18x7.5, 18x8, 18x8.5 do they all require the same offset of +55 or does that vary? Thanks r8byb

So it might not be wise for the OP to run that type of setup on the road?

I wouldn't say that, it won't cause him any problems at all.

Our steering is light anyway in my opinion.

Our vehicles have a 50/50 weight distribution so it makes logical sense to run the same wheels and tyres on all corners.

I can't comment from a position of substantive data to support this but I did know a lotus chassis engineer and he said that the usual reason for a stagger is that it allows a certain amount of under steer and 'normal' drivers can handle under steer better than over steer. So putting thinner tyres on the front can allow for more predictable control when they over cook the corner. This is not necessarily the optimum ideal handling position but ensures some 'safety' margin.

so really I should be fine with that wheel choice then... plan on running 215 tyres up front and 245 on the rear.

I think its a bit of a grey area for the average driver unless you know the ins and outs of geo/car set up. I used to think I knew enough to get me by but since getting the S I've realised that theres soo much more to learn!

thanks for the comments/advice.

If you run 215F and 245R with only half an inch wheels width difference you will have a large difference in tyre bulge front to rear. Why not get some wheels that fit better and would allow you to run optimium tyre size if your buying some?

By optimum I'm referring to Hondas description of this on the CR, which was 255/45 rear and 225/40 front. Optimally I'd be looking at 8" front 9" rear if you want to follow Hondas recommendation, or 9" all round if you want the extra front end grip!

You can run 18x9 all round with no arch work?

Thats pretty impressive for a car that original came with 16s!
