HELP! need WIDER tires!

My father & I use to argue about this all the time.

P265/70 R17

P265 = width in millimeters
70 is the height to width ratio
17 = the diameter of the wheel in inches

In other words to get calculate the sidewall height you multiply 265 X 0.70 = x millimeters

So the difference between a P265/65/17 and 265/70/17 is that sidewall height only which of course is directly related is overall diameter.

Actually, that's not true. The 265/70 is wider/larger than the 265/65 ...

If you look at the specs on the REVOs, the tread width on the 65s are 8" wide and the 70s are 7.8".

Simple; the lower the aspect ratio the wider the tire and shorter the sidewall. Sometimes the overall width (not tread width) will be wider. You don't need to calculate it 99% of the time. :confused:

I'm running 275s ... you cannot fit them unless you have a lift, and unless you are willing to chop off a lot of plastic. Even with 4" of lift, you'd need to cut a good deal to fit 275s or 285s.

You and 04runner have 275/70R17 GoodYear MT/R. You also have 4" Lift and 04runner 2.5". How it comes that he fit the same tire as you without trimming and you cut some plastic. Am I missing something?
 
I don't have 4" of lift anymore, but when I did, I trimmed the plastic because during offroading, the tires rubbed at full wheel-lock when they were stuffed in the wheel well. (and i didn't like the grinding sound it made when the lugs were chewing up the plastic)

Plus, Good Times (Lance) said it would be necessary to trim those parts - the plastic cups - (and said that before I had the tires).
 
You also get differences in wheel alignment.

Moving your wheels forward or back during a wheel alignment can make a difference.

How about this size? I was looking also. stock is 30.6

285 60 17 = 30.5

the width would look nice I think but unsure if it would rub width wise.
It is listed as plus zero

Not sure if it would rub or not, compare tire widths and heights at tirerack.com. Without a lift the largest tire that can fit should be no larger than a 265/70. Keep in mind that most 285 tires won't fit a 7.5" rim which is what the 4Runners have. Do a search for 275's and see if you like that look...

I know that on my 3rd gen could use 285 75 16's on stock 7" because many at yotatech ran them on lifted runners. our 7.5 rim I would "think" could accomodate a 285. I was wondering about rubbing due to the width. When I'm ready, maybe I'll just take the plunge and try them! The height in 30.5 which almost stock but miata calculator doesn't show section width. I'll check at the tirerack. Thanks!
