Question about tire size?

Would a 30 X 9.50 be bigger than a 255/70/15 tire?

So, some tire expert may correct me but my guess is that the 255/70/15 is slightly smaller.

255 (10") = tire width
70 = aspect ratio (side wall is 70% of width) = 7" high sidewall
15 = wheel diameter

Add them up
sidewall + wheel diameter + sidewall
7" + 15" + 7" = 29"

so... 29" high x 10" wide

30 x 9.50 is 30" high x 9.5" wide

Just a thought - please correct me if I'm wrong.

Yep, that's correct. The 30x9.50 size is a little taller and a little narrower than 255/70s. Click on my sig for pictures of my truck -- it's got the same wheels as yours and Michelin 30x9.50 tires -- so you can see how they look in comparison with yours. I like the height of mine, but want a little more width. My next set will probably be 31x10.50.

That's what I've got in BF Goodrich All-Terrain T/A's. I like the look and they hook up pretty good. I'm looking forward to using them this first winter.

Are you really sure 31 X 10.50's is gonna fit though? That's really what I want and I have been doing a bunch of research , but half the people tell me it will fit and be fine and the other half says it won't!

Regarding the half who say it won't work, what do they cite as the problem? The 31x10.50 size came stock on SE-V6 Hardbodies, so the truck and suspension can physically handle that size (easily). The only "hang up" in your case (and mine too) is the stock 6" wide wheel, which is a bit narrow for that tire size. But I don't believe that's really a concern because I've personally seen 31x10.50s mounted on the very same wheels we have. Your truck looks like it's already sitting at or just above normal ride height (unlike mine; I had to "restore" the ride height on mine with the torsion bar adjustment), so 31" tires will fit very nicely. Ideally, you would have a 7" wheel instead of a 6" wheel, but if you only have the budget for tires...

If you're still worried about 31x10.50 tires not fitting very well, 30x9.50s fit nicely...just a smidge too narrow in my opinion. 265/70/15s would also fit very very well. They're nominally about 30x10.40 tires (if you were to convert to standard measurements). That's the other tire size I am considering when I get new tires next spring or summer. Bridgestone makes the Dueler Revos in both sizes, and that's the brand and model I'm tending to lean to at this moment.

Adding to what Jason said. As he stated, SE's came with 31's.

Pathfinder SE's also came with 31's. Pathfinders sit lower than Hardbodys (1" or 1.5" lower) and they fit fine, so you will have no problems with 31s fitting on a taller Hardbody.

Yes, and I forgot to mention that all of the trucks (that I've seen) that had 31x10.50s from the factory were mounted on 7" wide wheels. In the early and mid 1990s, the most prevalent wheel I've seen have been the 3-spoke block wheel (the "lego wheel"). Starting in 1996, they were the alloy 5-spokes (which I think are fantastic looking wheels). Anyone wanna trade their 5-spoke alloys for my 6-spoke chrome steels?

I have a variant on the tire size question, if I may. I have the 30x95R15 tires on my recently acquired '95 Nissan King Cab 4 x 4 but the TEMP tire is a P215/75R15 on what looks like the same wheel. I don't quite understand why Nissan did not use a standard tire that matched the others. The next time I deal with tires, I am going to replace the TEMP tire with a matching size. Has anyone else here dealt with this issue?

The temporary spare really doesn't have to be the same diameter, although it should be relatively close. The only harm you might get into if you have a mis-matched tire diameter is if you have a Limited Slip Differential or if you need to run in 4 wheel drive for any reason after you've installed the spare tire. If you have an LSD and you get a flat on the rear, you'll need to swap the spare to a front tire to avoid damage. But I think that if your truck came with an LSD from the factory, Nissan mounted a full-size spare.

Their reasons for using a relatively small spare tire are very good ones...cost (good for them), weight (good for you), size (good for you), and ground clearance (good for you). I have a Class III receiver hitch on my truck and the rear of the receiver plug sits pretty close to the back edge of the spare tire. A tire that's much larger wouldn't really fit. If you don't have that concern with your truck (space or LSD issues), your only downsides of mounting a full-size spare back there is the added weight and slightly reduced ground clearance (if you mount a 9.5" wide tire vs. the 215mm tire, which is less than 8.5" wide).

And beware -- I also think the spare tire wheel itself is a 15x5.5 vs. a 15x6, like your other wheels. Check to make sure the size of tire you want to mount will physically fit on that rim.

Check out this page for tire size comparisons. Or you can do a google search for "tire size calculator"
