I got a 2001 Type S. I want to put some 18 inch niche rhine rims on it. I was wondering what size tire would be best? Should I go with 40 series or 45 series?

 

most people use 225 or 235/40-18. the latter is closer to stock diameter.

 

i'd go with 45 series on 18 inch rim, it'll give the rim a lil more cushion esp if you hit a pothole, let the rubber absorb more shock. and it's closer to stock diameter so it shouldn't throw off your speedometer too much.

 

Thats what I was thinking. I used to have 40 series on my last car and I got a bent rim from going over a pot hole. I was thinking that a 45 series tire would give me a little more protection against that.

 

What is the offset of those Niche wheels?

 

i have 225/40 on my 18" wheels and it seems to be fine. but then again i live in so cali where the roads are all fairly nice here

 

I have Sumitomo 225/40/R18 and they work great...but after I put them on I realized I needed a comptech drop...

 

Get the 40 series, grip is outstanding !!

 

This may sound dumb, but what's the difference in grip between a 40 and 45 series?
