I have a 05 4-door 4-WD. The current tire size is 235/75/15. I just put new tires and rims on my sons jeep. The tires we took off are only 9-months old, But their size is 265/70/15. Has anyone ran this size of tire before on their blazer? Mine is stock. Instead of selling them, I thought about replacing mine with them. Since I'm going to need new tires soon. Thanks.

 

Although the 265 should be around 1/2" taller the width (up to 2" more) could be a problem with hitting the lower control arms in a tight turn. See what kind of clearance you have now. Hopefully someone who has tried the 265's will reply.

 

Thanks I fixed it. Also the 265's are an inch wider too.

 

The tire sample I looked at the specs for showed a 2" width diff. Another I just checked shows only 1" so if yours are only a inch you may be able to adjust the stops out to keep from hitting that lower c/a.

 

Thanks for looking into that for me. Im having a graduation party right now for my son and things are hectic around here now. LOL probably be back on tonight. Its appreciated!

 

The answer to your question can be found in the Miata Tire Calculator on the net. Google this site and you put in the stock size for your Blazer--- I am sure by now you see your typo 235/135--- and then to compare the diameter you put in the tire size of the 'take off'. It will give you a side by side comparison of the two tires. If they are more than 1/4 inch or maybe 1/2inch apart, it will affect the speedometer....and maybe the trans shifting.

 

There's a lot of things that can affect it. A normal street type tire will be a lot less likely to rub than an AT or MT type tire of the same height because an AT or MT will have a lot larger shoulder. I ran 255/70/15 touring type tires for 3 years with no problems on my factory height 4 door 4x4 Blazer.

This is just a guess because there can be a lot of variation even in factory height Blazers, but with a 265/70/15 I'd bet that you will probably touch the sway bar and the frame when you turn the steering wheel right to the stops and hit a bump. You might also touch the back of the front fender. All of those points could be mitigated if you're wanting to lift your Blazer a bit.
