Tires... D'oh!!

Hey Y'all,
I have a tire question that I didn't find an answer to in a thread.
My ride is a daily driver. I off road a little, I am not a dune mobbin loon anymore.
This is a bone stock 2017 Tacoma DubCab TRD Sport 4wd. He came with 265/65R17 tires. I am wondering if anyone has installed larger tires and not had clearance or rubbing issues. If you have, what size did you get?
If I have to retain the stock size, so be it. I currently don't have any plans for suspension or body lift. I also have a 2019 4Runner TRD Off Road. My 4Runner is first in line for mods.

Thanks in advance for your constructive input.

265/75/16s on stock rims is the biggest w/out rubbing without additional mods.

 

If you plan on keeping the OEM 17-inch wheels that came with the Sport then probably 265/70R17. I changed out the OEM rims about a week ago to the 4Runner TRD Pro wheels and kept the original tires since they only have a little over 4,000 miles on them. When it comes times for new tires I'm staying with the 65s. Want to make sure I can keep my mud flaps. Same situation as you. Bone stock suspension, no plans to lift and the most off road I go is the occasional dirt or gravel road. Will go with a slightly more aggressive tire than the highway tires it came with but nothing too noisy since it's a daily driver. Probably the Michelin LTX AT2 in the stock size.

 

If you like pizza cutters, you can get a 33" 255/80/17 under there.

 

Thanx for the input. The clearance would be cool, and I wouldn't mind my Taco being a bit higher. I didn't think about thinner tire with larger profile.
There's NO WAY I'm putting a low-profile tire and bigger rim on my Taco. That looks like a Matchbox car to me. Personal preference, I think smaller sidewalls on big rims look goofy on 4wd truck. On my Subaru STi, they looked dope.

 

It will do very well with the tires you have while you get to know about your new truck. Take your time and study up, plenty of information on here and You Tube about tires etc for these trucks. Chances are where you live, plenty of information available just by getting out on the trails etc and talking to 4x4 folks.

 

265 70 17 on stock rims without worry of rub or charging the scrub radius significantly.

With no other mods, if you were to do 255 80 17, this moves your positive scrub radius 11mm towards the negative. This will net you a zero to negative scrub raidius. At zero it will feel squirmy. A negative will cause the tires to toe in under dynamic force(cruise, acceleration, braking).

A large part of the reason our trucks, equipped with a 'minimal' amount of positive scrub, specifies a +0.05 toe-in measurement is dynamic force will deflect the rubber bushings and zero toe out under cruise conditions. If you introduce even more dynamic force in the form of braking or acceleration the effect is minimal.

If it had negative scrub, the tires will want to toe in under cruise; and toe-in even further under acceleration and braking if it has a 'large' amount of negative scrub. You could try to compensate with a toe-out alignment, but that's the wrong way to go about it. The correct way would be to go from your stock +30mm wheel to a +19mm offset. You could also do >+19mm offset; better to have additional positive scrub than zero or negative scrub in a rwd vehicle. But that comes at a cost as well.

Or, whatever...

 

good post.

I dont run 255/80/17 myself, but was pre-contemplative for a winter set in OEM +30 offset wheels.

TBH, i didn't know enough if whether or not this would get into zero/negative scrub radius territory. Thanks

wondering whether anyone running this on OEM wheels experience handling detriment, as that certainly would not be desireable.

With negative scrub, I could see it being bad in winter, in certain situations...
Say you're going around a corner and the outside wheel goes into bumpsteer, it'll toe-in, screwing up Ackerman, snapping the turn sharp.
