Title: 225/40/18 vs 235/40/18 pros and cons
Post by: RobD on September 17, 2004, 05:29:35 AM
I'm sure this has been covered many times all over the other sites but wanted to check with my local crew as to their thoughts on running one or the other size.

I'm looking at the Kumho ASX (all season) and concerned the 225 will not look like it fils the rim enough but also concerned that the 235 might be too wide for decent "all weather" traction.  I do have 15" snow tires if i need serious snow traction.

I have also considered the Conti extreme and the Toyo Proxes 4.

Let me know what you folks think.

Thanks
Rob

overall width depends on rim width.  If you are running 8" or less, 225 is adequate and all you really need.  For winter, narrower tires are better for traction, more weight per contact patch on a narrower tire, etc.  If your rim is 8.5" or greater, you will need to run 235 at a minimum to properly fit the tire on the rim.

I love the Conti's, but you already know that.  Many people here have them, Hawk, Gragravar, me, and other friends with various Volvo and other Audis.

Jon - sorry i forgot to add I'm getting Daves Flik Artics that are 18 x 8.5".

So the 235 would be the way to go?

yes, you must go 235 for the correct fitment.  Some stretch 225's, but in my opinion, that is wrong.  even 225 on 8.0" is a stretch.....

OK, now I am going to chime in.  Since I am looking at Randy's 17x8 I am under the assumption the 225" would be fine.  I have been to Tire Rack and that is what they suggest.

Correct.

Interesting, on Tirerack they mention for all of their 18x8.5 the tire size of 225/40/18.

Get 275's and you should be safe...you won't have to worry about curb rash either :-P

Rob,

Get 235's....it's as simple as that. You should really just have dedicated wheels for winter and summer. You don't want your 18's exposed to all the crap on the road during the winter anyways...

If you do decide to go with an 18" all-season tire, consider the Falken ZE-512's... they've gotten great reviews and have a wear rating that can't be beat.
