Tire size

hey y’all I’m looking to upgrade my tires on my first gen xtra cab. I’m all stock right now. What tires and size would you recommend?

 

I got new tires and wheels for my 1st Gen as soon as I could. Went with 16in wheels so I can do the Tundra brake upgrade, and P265/70-16 TOYO AT-II Open Country tires. Forgot to mention that mine is Xtra-cab, 4x4 with stock suspension; NO rubbing at all.

 

4x4 (or 6 lug prerunner) I assume?

If that's the case, 265/70r16s (31" tire) is the largest stock size, and going any larger will likely rub somewhere. I have 265/75r16's (BFG KOs) and those rubbed the frame behind the front suspension at full lock at stock height AND with a ~1" lift (5100s on middle setting).

Going with a mild lift will help prevent it form rubbing in a parking lot, but keep in mind most lifts maintain the same suspension geometry (just make it higher) so the tires would still rub, just under some amount of compression instead of at normal ride height. This is assuming you have stock wheels and otherwise stock suspension.

Adding things like wheels with a smaller backspace, or aftermarket upper control arms will push the susp. a little farther away from the frame, so frame rubbage would likely be reduced/eliminated. Go too far and then you increase the chances the tires would rub on the fenders. Then you need things like the "pinch weld mod" or other trimming.

But without knowing what kind of driving you plan to do, and in what kind of terrain, we can't really recommend a size/type of tire.

 

On my '02 I went w/ 16 " wheels & 265/70-16 " Cooper Discoverer AT3's - Does a nice job on the street, snow & gravel roads.

 

Well I have a 4x4 and want to get more into off-roading. Not needing it as a daily sonjist looking for some recommendations

 

Cooper ST Maxx 265/75/16 got them on less than a week ago but so far love them

 

So I take my tire shop guy was being a bit too liberal when he said i could put 275/70R16 BFG ATs mounted on an 16x8 wheel (Method MR301) on a stock suspension 2003 PreRunner? Yours is a tad higher, mine would we a tad (~.4") wider.

 

Generally a shop will go with what the owner's manual says to reduce any type of liability. Which is exactly what one should do if running a shop or a company.
265/75/R16 (32's) will be fine - though some places (like costco) won't install them because it's not specified in owners manual

 

Well, you can technically put 285's on it, but the tires will rub a LOT.... My 265/75r16's rubbed the frame with the stock wheels which are , which by my math (35mm ~ 1.4", 3.5" + 1.4") is 4.9" backspace. I always remembered it being a 4.5" backspace, but whatever, wouldn't be the first or the last time I've been wrong, lol


So, let's see, that wheel is 8" wide with zero offset = 4" backspace.

The smaller backspace of those method wheels means the tire will sit farther from the suspension and frame, which means you'll less likely rub the frame like I did, but that wider tire + wider rim + smaller offset also puts the tire closer to the fender, so you may end up rubbing there, too.

So will that tire "fit"? Sure. But it will probably rub somewhere.

 

On ther otherHowever the tire manufacturer will

Stock wheels - steelies or alloy rims? (trd) Or are they the same?

 

I *think* they are the same (if comparing 16" diameter ones), but I have alloys...

 

oops, and I meant to say 4.9" backspacing, not offset... (will edit)

 

I have 275/70r16 on my 2012 prerunner with stock suspension and stock wheels. No rubbing at all.

Today I will get 265/60r18 on fuel beast 18x9 -12 wheels!

I have always liked the 265/75/16 size. I ran them for probably 5 years on stock suspension. I then added ~2” lift and have run them all but once when I swapped to 255/85. They would rub slightly with stock suspension. In my current setup I don’t think I’ve ever had a rub that was noticed. 265/75/16 KO2’s, they hare E rated and heavy but since swapping to E rates tires I don’t get flats like I used to with C rated tires.
