I would like to size up my 16" rims with 265/75/16 tires to a 17" rim. Seems like more choices to buy in 17" size. Just want to know if this can be done on my 98Runner Limited 4x4 V6, without any issues.
Advice is greatly appreciated!

 

You just want to run 17s instead of 16s? doesnt matter at all. Just need to lower your tire height if you dont have room for a little extra meat.

problems happen going down, not up..

 

Thanks for your advice. Just so I'm clear on this , there is not effect to speedometer, brakes etc?
Also what siv
size tire is recomended with 17" rims sized up from stock 16" with 265/75/16 OE size?

 

No issues with anything. All those problems are when you oversize the overall diameter of the tires rather then the wheel. Like going from 33s to 35s I need to do the speedo calibration and my brakes are already upgraded but that would be something for someone to look into.

Im not that great with metric sizes so you would have to wait for an answer here or look it up on any tire page online..

 

Well, you can get close by doing the math.

265/75/16 meansthe tread is 265mm wide, the sidewall is 75% of the tread width, and the inside lip diameter of the wheel is 16 inches.

So, the sidewall height is 0.75x265mm, so that becomes198.75mm. Times that by two and you get 397.5mm.

Roughly 25mm/inch, so

397.5mm/25 = 15.9inches

15.9 + 16 = 31.9inches. Lets call it 32 inches. This should be somewhat close to your overall tire/wheel diameter. Now, this is only an estimate because tire manufacturers vary a biton tread width and sidewall height from what is imprinted on the tire.

So, to keep from having to mess with your speedometer, you need to find a tire/wheel combination fairly close to 32 inches. Assuming you stay with the 265 width, lets see...

32-17 = 15. Half of 15 is 7.5, times 25 meansyou have 187.5 mm sidewall height to achieve. Staying with a 265mm tread width, that means you have to go down to a 70 series tire. Not much diff btwn 70 and 75 so no big deal. If you want to go with a wider tread, then do the math accordingly.

Oh, did I mention that tire manufacturerers varya bit on read width and sidewall from what is imprinted on the tire? They do, so all this number crunching only gives you a rough estimate.

 

Wow that realy gives me something to think about!

 

By the way, you can go to the Tire Rack website, and browsefor tires or wheels or tire/wheel packages. They have an option where you enter your vehicle information and you can see a picture of what differentstuff looks like mounted on a 98 4Runner.
