I am planning on getting some wheels soon and was planning on putting 235/40-18, but after reading so many threads about how rough the ride is, I'm starting to consider getting 235/50-18. The wheels I'm getting are 18x7.5, so techinically the 235/40 would be out of spec, but the 235/50 wouldn't. I know a lot of people on the org are running the 235/50-17 and like it, but would 235/50-18 look too big on my 2k max. Any input would be appreciated, especially from people running the 235/40-18 right now. How do you feel ride quality is? I am on H&R's right now too, so I don't know if I would have to worry about rubbing on the 235/50. Also if I go with the 235/50, is it difficult to correct for the speedo error on our max. Sorry for all the questions, and yes I used the search function already.

 

In general, the difference would be about 1.1" in overall diameter. That means about a .55" increase on the outer visual dimension (and actual dimension of the tire). I personally am running a 225 55/17 and don't think they look too large (they are only .1" less than the 18's you mentioned).

A lot will also be determined by the wheels chosen. I mean if they get too ghetto-ish they might end up LOOKING huge when in fact they are not that much larger.

 

I'm thinking of going with these rota battle's http://subydude.com/parts/details.php?102. In the correct bolt pattern of course and in 18x7.5. What do you guys think?

 

How much do those spokes 'bend' outward? Looks like quite a bit in the photo.

 

Those tires would be way too tall for the Maxima. 235-50's are even too tall on a 17" rim.

If you want to ease the rough ride quality somewhat, a good alternate to 235-40-18s would be 225-45-18s. Not many tires to choose from in that size, though.

245-40-18s will also have a taller sidewall than 235-40-18s, so would also be a little more comfy. There are a ton of tires available in that size. 245-45s are not recommended for a 7.5" wide wheel, though. You would need at least an 8"er.

 

im running 235/45-r18

 

By what criteria are you judging them too tall? Your opinion of looks? Rubbing (which they don't)? Other?

Some of us just don't like low profile tires and large wheel well gaps.

 

Here is a page that has two intrepids with 235/50-18 tires on them.http://www.discounttiredirect.com/dodgePage.html They don't look that bad. I am really just leaning toward this size because of hopefully a smoother ride and they have some at tirerack for $94 per tire. Igor, I would ideally want to run 235/45 like you, but there don't seem to be that many choices in that size. Anyone know about the speedo correction because according to the miata tire calculator I would be off by 7.7% with this size.
