Is there any difference I need to know about. Picking up Kuhmo Ecsta ASX in 2 weeks and the guy is pushing 235.

My current wheels are Pilot Sport 225/50/17.

Thanks a lot for any help!

 

the 235 will make the tires wider, but they will fit stock rims. i had 235/45/17 on my car and the tires were wider.

 

I understand that the 235 are wider, but are there any positives or negatives of wider?

 

Also, rims are Motegi MR7 17x7

Does this effect width choice, tire guy seems to think not...is he correct?

 

For the best performance the wheel width should be 90% of the tire width. So the 225 would be best for that particular width wheel, but 235's work well too.

On a 4th gen I would rather have 8" wide and at the very least 7.5"

 

Thanks! Stuck with the 7" so 225 it will be.

 

I had 225 45-17s at one point looked ok, now that I think of it the 225-50 would have been better looking.

 

Why do you say that? I personally like the looks of lower profile better...damn now you got me thinking!

 

The 235 will look fat(and phat) on a 7" rim. I currently have a 245 on my fronts which are 8". The look is kinda cool. It gives it a really hardcore impression. But the gearing suffers a bit. 235/45 is closest to the OEM OD. The 225/45 will be a smaller OD which will improve the gearing but it will look small in the wheel well.

OEM OD= 25.66"
235/45/17 OD= 25.46"(Closest to OEM and most grip but the gearing isn't any better than stock)
225/45/17 OD= 25.1"(Best gearing out of these options)
225/50/17 OD= 26"(Fills wheel well the best)

Make your decisions from those #'s. You won't have a problem running the 235. I say go for it. And since your 5Spd I recomend it even more. You need all the grip you can get and the gearing is much better than the auto.

 

FYI, the Kumho ASX does come in 225/50R17. The part number is 7583.

 

Any comments on 235/50/17 with OD of 26.3?

Or would 235/45/17 be better?

 

You would be very slow with w 235/50/17. You shouldn't even consider that an option. That size will look even more fat than the already chunky 235/45.

 

Cool, thanks a lot for all the info. Very helpful in helping me make a decision!

225/50 or 235/45 will be the decision in the next week...finally will be back on the road after 8 months of storage while at school!
