Title: tire size
Post by: bennyblanco2750 on December 15, 2010, 08:15:48 AM
I was wondering if their is a difference in tire size. I was at the supermarket the other day and i happend to park next to another aztek. The aztek was running 215 65 r16 and im running 215 70 r16. When i go on tirerack.com, their are more options available in the 215 65 r16 size than the size im running. My question is would i notice any difference in handling or performance if i went with the 215 65 r16? I have viewed other post on aztekfan club and have found it to be very helpful. I greatly appreciate any advice on what i should run with.
P.S. i currently have a 2004 aztek awd if that matters much in the decision making.

Going from 215-70-16 to 215-65-16 will make the tire .9 Inch shorter so there may be a small difference in handling. Due to the smaller tire size, when your speedometer reads 60 mph you will actually be traveling 58.2 mph, or 3% faster than your actually going.

Also welcome to the Aztek Fan Club!!! Enjoy the site!!!

Also if you get really big tires you might run the risk of rubbing the inside of the tires on the wheel well when turning.. I have pretty large ones, and thus when I turn my wheel all the way it does just barely touch the inside wheel well..

And actually when I upgraded to my big tires from the stock ones for some reason my speedometer actually evened out. Whenever I go by a speedometer thing on the side of the road it tells me that my speedometer is now spot-on..

oh yea and my new tires are sized: 235/50/18

Its amazing how much tire size will affect the speedometer.  At one point I was running a 17x9 Borbet rim with a 245/45/17 on our Tek and my speedo was 5mph faster than what I was actually doing.

I appreciate the feedback and have decided to stay with the stock p215 70 r16. i ordered a set of kumho kr21s for my aztek. Have any of you had these tires before and if so how were they?

I have a set of KR21's on my recently deceased Aztek. They seem to be pretty good tires for the price. In the six months I've had them I haven't hydroplaned once. They also hook up a lot better than my old tiger paws.

215 60 16?
Those would be way to small. Are you sure you don't mean 215 70 16?

I probably have the widest tire on my Aztek than anyone else, i have Toyo Proxes St. size 255/50/R18
They dont really rub much only like once in a while but rarely
In the winter though they get snow stuck on the side of the wheel well all i do is kick it off and thats it.
By the end of the winter here in Chicago i might go with some Goodyear Assurance i bought some for my dad and they are great
The only problem is that i need to go smaller since Goodyear doesnt make the Toyo's size  :no:

Wider tires and lower profile tires in the winter actually perform less favorable than that of a narrower one.

Sorry I havent been for awhile. Ya know, that wouldnt suprise me if they were too small, they looked PUNY! I am quite sure thats what they were sized. I actually couldnt remember when I was originally posted so I looked back at an email from a craigslist ad I posted to see what they were sized. But maybe I just wrote down the wrong size. I would check but they are at my parents house right now..

Allow me to just use this thread rather than starting another one...

Brian o's going to kill me with my two dozen questions!!!

So my question.....

CAN ANYONE CONFIRM THAT THE WHEEL WELLS OF AN 01 IS ANY BIGGER THAN OF THE OTHER YEARS???


Title: Re: tire size
Post by: 97drexelgrad on April 09, 2011, 12:29:33 PM
With a few minutes with a sawzall the wheel wells will be larger.  Otherwise they are identical.

So I've had the kr 21's for about a year and a half now and have no complaints. They handle good and are quiet on the highway? My question is should I replace the two front tires or rotate them? I had an alignment done twice but never balanced or rotated. The driver side tire looks good but the passenger side is wearing on the outside. Back tires look like new. Should I rotate the back tires to the front or just get two new ones? If I replace the two tires should I get the same tire or could I get a different brand and not experience any issues?

Well ive replaced my tires again on my aztek. I went to mavis and went with Westlake 215 70r16. So far they seem pretty quiet while driving. Forgot how it felt to drive with a new set of tires with an aligment. I purchased the optional road hazard that includes free tire rotation so I have no excuse not to have them rotated. If any has had these tires before let me know what your experience was like.

I just put new westlake tires on my travel trailer.  They were a good price, had good reviews and are wearing well so far.   The tires that came with the trailer were junk- Vail brand.  We're wearing so poorly I didn't feel safe towing.  The tires were shot after three years and only about 3500 miles.   
I have about 1000 miles on the new Westlake tires and they still look brand new

Hello folks.  Newbie here.  I have a 2001 FWD with Traction control.  It has 215 70 15 and I really want to beef up the tires so I can get off road a little more and just make it look bad ass:)  I read the threads and went to the link but am still lost.  My question is.  Without upgrading my rims to 16 what is the biggest tire I can mount on my rims?  It handles really well now but im willing to take on a little sloppiness as it is a pleasure machine for me.  My dad has a 2003 with 16 and my Mom and him luv it!  Looking to get tires ASAP as its starting to rain here in Vancouver and I hit Whistler allot and need some tread.  Thanks I  advance I appreciate any info.  Cheers.

You could mount 33X10.50 tires on your 15" rims... They will never fit on the Aztek though. You aren't going to be  able to get a lot of lift just by changing tire size. Remember that if you move to a tire that is 1" taller than what you have, it will only pick you up 1/2 inch. The other 1/2 inch is on the top.

Other challenges you may have are an inaccurate speedo and a loss of torque. you could pick up a set of factory 16" wheels pretty cheap on Craigslist - Probably not Aztek specific wheels, but many Pontiac, Buick, Oldsmobile and Chevrolet wheels will fit as they share a lug pattern. (I believe it is 5x115)

Now, if you are willing to fabricate a lift kit and regear, the sky is the limit!

If anyone ever comes around looking for tire size info. I fit 225/70/16s Hankook AT2 tires on my Aztek with no rubbing issues with the spring plate or turning radius. It is very close though. Wheels are aftermarket 16x7 wtih +42mm offset.
