Another fitment question

Good day Gents,

I'm in the process of buying some boots for my Canyon and I have a question about fitment on the oem 16s. I'm looking at Wrangler Duratracs in 255-70-16 size and I am curious if I'll have any problems fitting them on my oem rims. The truck is a 10 Canyon SLE crewcab Z85 with the 16x6.5 rims. When I do a truck specific search on the usual sites the Wranglers aren't listed as compatible, but the tire specs on Goodyear's website state that they will fit 6.5-8.5 wide rims, I'd love some wider rims, but it's not in the cards this season. I'm wondering if there is any rub issues with 255s on the oems and if it's an offset issue, or due to the slight increase in diameter is what's limiting the availability of these tires on various tire selectors? Will they fit? :cheers::cheers:

That's a tough one. I think you're going to need to wait for somebody with that specific size to say for sure. We are all really good at speculating the "it should" answer.
If you drive a 4x4 I believe it will be close with the increased diameter and width using the stock wheels. The offset could be a problem as the wheels are tucked.

If you plan to purchase the tires from a local shop I'd then suggest a test fit prior to purchase, if they fit then go forward with the sale.

If you have a 2wd, I don't think it's a good option as the tire is significantly larger than stock.

255mm on the 6.5" wheel seems a little suspect, but if you've already looked it up for that tire then I suppose it's good. Just seems pretty narrow (to me).

I forgot to mention, it is 4x4. I was surprised to see that the fitment was 6.5 on the low end myself. I should just buy some winters in oem spec and wait for knobbies and see if I'll be doing any lift or aftermarket rims...

Thanks man.

The difference in your stock (235/70-16??) to the new tire isn't too much then. 20mm wider, 10mm on each side of center. The diameter is close too. Assuming I listed the correct stock size, the Duratrac is only about an inch taller. And the speedometer is only off by 4%.

Also, without having any lift, the tire should still look appropriate -not oversized for the fender wells.

The tires on it are 235-75-16, 255-70-16 was the closest in diameter I could find in that tire. I'm concerned mostly with full lock rub, which I'm not sure of with the extra 10 mm on the inside combined with the stock offset. I will not use spacers as I don't trust them, so not an option. The extra 10mm on the outside would be inside the fenders still and not poke at all, or not much more than 5ish mm which is still road legal up here in Alberta. Plus being on the narrow side as far as rim width, though according to Goodyears info, is still fine. I'd be happier to be dead centre at 7.5 inch wheel width, but no new rims this year. Hopefully someone has run this combination and will chime in.

Ahh okay, I thought they reduced the sidewall to 70 series when they went to 16" wheels. My mistake.

The two tires should be about the same, for all intensive purposes. I don't see why you can't turn you wheel to lock now and see how much clearance you have. By the math, the two tires are nearly identical height which would make the contact point pretty much the same. If it appears you have room with the current tire I'd assume you can clear the Goodyear's too. Keep in mind too the Goodyears do have the mud type lug patter on the shoulder. That may make for a good catch point.

I guess nothing left now but to go ahead and buy them.

Wierd. Your profile says you have a zq8... which is a 2wd.

I don't think the width will be a problem at stock height. You can always turn the wheels all the way to the right and left then have a look to see how close you are to the sway bar with the 235s on it.

Edit... just realized 08Canyon gave you the same advice

I'll have a measure in the morning. Thanks Sirs! And duratracs are on sale...

Just a quick update FYI,

255-70-16 wrangler duratracs fit fine with zero rub on any hard parts on the oem SLE Z85 16x6.5 rims. The only contact between tires and anything is if you have the oem molded mudflaps with frozen road slop stuck to them. Which I would expect even with the 235-75-16 sized tires if it builds up enough. It only occurs when turning. I may switch to flat mud flaps at some point, but it's not a big enough issue if you kick the ice out when you park.

Thanks for the assist people.:th_woot:
