lint Posted August 23, 2010 Share Posted August 23, 2010 I've got a line on some ugly and cheap OEM steelies for my winter set....maybe that might be the route to go instead of the Toyota rims I was originally considering. If I go to 16" from the original 15" how does that affect my gearing? Clearance? Anything else I need to consider? Pros and cons are welcome. Thanks for your opinions!

Larger wheels won't change anything. Outside tire diameter will be the thing that would be an issue with gearing. Link to comment Share on other sites More sharing options...
silverton Posted August 23, 2010 Share Posted August 23, 2010 Sadly, with your stock size (SE) being the 31x10.50R15, there isn't really anything close in a 16" rim that will keep your odometer mildly accurate. There is a decent selection of 275/70R16's on tirerack.com They are .58% off So every 159.97 indicated km's you'd have actually traveled 160.9 km. So really not that far off. Hope that helps!

Kingman Posted August 23, 2010 Share Posted August 23, 2010 (edited) A 265/75/16 is a 31x10.50x15. Edited August 23, 2010 by Kingman Link to comment Share on other sites More sharing options...
silverton Posted August 23, 2010 Share Posted August 23, 2010 A 265/75/16 is a 31x10.50x15. A 265/75R16 is actually a 32x10.43x16 Link to comment Share on other sites More sharing options...

lint Posted August 23, 2010 Author Share Posted August 23, 2010 you guys rock! Thanks so much for your help, that would've taken me at least a day to figure out! Now I can go wrench on other stuff. Link to comment Share on other sites More sharing options...

Hope that helps! .58% deviation is nothing, most tires deviate more than that just by different manufacturers. Tire wear over the life of the tire is far more than that. The odometers on the vehicles aren't even that accurate. B Link to comment Share on other sites More sharing options...

silverton Posted August 24, 2010 Share Posted August 24, 2010 Going from 235/75's to 31x10.50's I add 10 miles for every 100 miles I drive. Link to comment Share on other sites More sharing options...

Precise1 Posted August 24, 2010 Share Posted August 24, 2010 *snort* Going from 235/75's to 31x10.50's I add 10 miles for every 100 miles I drive. It is 8% difference, so add 8. B Link to comment Share on other sites More sharing options...
Kingman Posted August 24, 2010 Share Posted August 24, 2010 A 265/75R16 is actually a 32x10.43x16 In theory yes, but after standing tons of 31s and 265s together when I worked at Les Schwab, I've found that they are basically the same overall size in width and height.

Oh I know that and I understand what you're getting at. But what I'm saying is, manufacturers measure their tires so differently that there's almost never a true-to-measurement tire and there's always a little bit of deviation in the physical tire size. I put a set 265/75/16s on a '97 caR50 and they looked great. It was also the same size tire that came off and I talked to the guy about it and that's all he's been running since he got the truck.

MrPlow Posted August 26, 2010 Share Posted August 26, 2010 I have 16" crager soft rims and 285/75/r16 mud tires the only problem I have is with my particular rim the off-set causes the tires to rub the frame after about a turn and a half of the wheel. Had I got 15" rims (with different offset) there would have been no rubbing but I already had the tires, and didn't want to buy new ones. I hope your wheels work out for you.

Don't mess with GPS, do the math... Revs per Mile: 720.4 Revs per Mile: 671.6 Sorry, it's generally closer to 7%. B Link to comment Share on other sites More sharing options...
