SR5 - Stock Wheels - How big can I go in tires to absorb road bumps

[brumey]

My goal is to increase the tire size to absorb road imperfections, bumps, potholes. Not looking for off-road capability, "poke", etc. Also, not wanting to change stock SR5 wheels.

I seem to remember reading a thread that has a 275 17 tire on it but apparently the tire spec requires a larger wheel so fitting it to the SR5 stock wheel might not be the safest thing to do.

So, how bigger can I go and get better road manners. Stock is 245 70 R17. Looking for larger sidewall and overall volume.

I get the impression that the majority of owners and wannabe owners on this forum what off-road, poke, lift. The each his own but I just want to tame the road that I am 99% on. Don't flame me about why I purchased a 4Runner, body on frame, etc. I fully understand that and stock, it rides better that my past unibody Ford SUV. If I want offroad fun, I'd by a Land Rover Defender and leave stock.

That's a lot of weird unsolicited commentary to just ask a question about tire size..

Anyways here is my SR5 with no stock suspension and no mods on 285/70/17 on stock SR5 tires with no lift or any other mods. Completely stock setup other than tires. They do not rub at all and the ride hasn't changed enough to worry about. They are Mickey Thompson Baja Boss A/Ts

Love the look! How do the Mickey's handle in the rain?

Not sure yet, haven't had any lol. They grip more around corners for sure when it's dry, that's about all I can speak of at the moment.

285/70R17 is the size in question, that some tire manufacturer spec sheets deemed too wide for the SR5 17x7" wheel. Just go 265/70R17 (31.5), 245/75R17 (31.5) or 255/75R17 (32) if you're worried about width

Thanks Nubbins_. This info is perfect.

Did you get the E load or STD?

The unsolicited commentary was to provide needed emphasis on the tire attributes and goals. As commented by "Nubbins_" There are potential issues going with too large a tire on the stock rim.

Your choice of tire satisfies your needs and looks good but I doubt it would contribute to a quite, compliant ride on the road. I could be wrong.

I have also heard of tire companies not having the correct OEM wheel size info and therefore could be recommending unsuitable tires.

I will be taking a close look at these sizes in a non-offload design, quality manufacturer.
265/70R17 (31.5), 245/75R17 (31.5) or 255/75R17 (32)

265/70 SL Open Country ATs on my SR5. They only weigh 40lbs and ride quality is great. I’ve averaged 21.6mpg over the first 1500 miles.

Yeah, unfortunately with the rig being so new there is not a whole lot of "perfect" info on them. When I bought the tires I was under the impression that 285/75/17 were the largest tire with no modifications, I ended up going with 285/70/17s of the Mickey Thompson based on price at the time mostly which I'm glad I did in hindsight. There is another thread of mine that has a lot more photos of the fit / "poke" of them which there hardly is any. The tire shop that put them on had zero concerns though as far as fitment and installation. Ride wise the only difference that is even somewhat noticeable is a little more bounce when going over stuff mostly due to the load range being E (which this truck does not need, again just happened to have the best deal on them at the time).

Mine are E load if you are asking. Which is overkill and makes the ride slightly stiffer. Not enough to really make a whole lot of difference unless you're hyper sensitive to it.

Try to run C or S class tires and check the weight of each tire in the specs. The E class can get very heavy 285 and up which will drag on performance and mileage. I run "275/70/18 C" Wildpeaks AT4s and they ride great.

I suggest reading your post again before criticizing an other’s writing composition
