Going up to 285 tires with my setup?

Wondering on everyone thoughts on tire size. I currently am running the toyo at2 265 70 16 on the eibach pro lift and old man emu HD rear leafs and was curious on what size I can go up to. Been looking into 255 85 16 cooper st maxx and a few other tire brands bf Goodrich km3 and the Yokohama MT wondering if I will be able to run a 285 or would it be too much and worry about having to re gear

 

I moved up to 265/75/16 and wish I'd done it sooner. They are same width as your 265/70/16's but about 1" taller. They are generally a little less expensive too. Any bigger and you'll need to start modifying the truck and will see noticeable differences in fuel mileage and power. I've never used 255/85's, but read that they can be made to fit with minimal trimming. While narrower, they are a bit taller than 265/75's. They are also much less common and your choices will be limited.

But since you're already lifted you should be able to go to 255/85's or 285/75's without rubbing. You will see loss of power unless you also regear. But this is one of the borderline cases. At that size many people don't feel the loss of power is enough to justify the expense to regear. Many do.

A 265/75 is also about as big as you can go and stay with a standard load tire, and in my opinion still looks good with a moderate lift. The bigger sizes are pretty much LT tires only. That will add around $100 to the cost of a set of tires and hurt ride quality some. The advantage of an LT tire is a tougher tire that will resist punctures better than standard tires if driven a lot off road. On a lightweight Tacoma most people are better off with a standard tire.

 

I ran 285/75/16 KM3 MT(16x7.5 +10) on 5100/ome885 on the lowest setting and did not rub besides front flaps.

 

I kept the weight down on my 285s and still get good mpg/power, if you can find a tire C or D load in the low 50lb for weight you will find that your truck will still perform good. It looks awesome! The only thing is that in a 16 inch wheel there are not many C or D load choices.

 

Almost certain you will need a CMC on a 2nd gen for 285's.

 

Depends on wheel specs, width, offset. Also if you have adjustable UCAs.

 

285s usually rub

 

Seems like everyone here has slightly different experiences with 285s and the amount of rubbing. General consensus over the years here (after hundreds if not thousands of threads on this) is a CMC and pinch-weld flattening is needed, though others have gotten away with just removing the mudflaps and trimming the flares/liners/bumper skin. How severe the rub depends on how hard you wheel, I suspect. How hard do you wheel?

Do you need to have 285s though? Or is it just a want to have? Only gaining roughly ~1/2" ground clearance going from 265/70r16 to 285/70r16. Would be better served to go 265/75r16. Within 0.1" diameter of the 285/70r16, still gaining that 1/2" ground clearance, but skinny enough to not rub.

 

I am still running stock wheels and will be upgrading the UCA here in the next month or so I just got brand new lower control arms. So I'm out on the 285s no need to have those. What are your thoughts on the 255 85 16s I have read about alot of people having great experience with that size being tall and skinny at the same time but if I go up one size from where I am now being a 265 75 16 wondering if I will be able to fill up the gap on the wheel wells and not have to worry about any rubbing issues at all.

 

When you start comparing tires that are borderline on fitting you'll get different opinions. A Goodyear tire may be slightly bigger than a Cooper tire even in the same size. An otherwise identical E rated tire from the same manufacturer in the same size will be slightly larger than a P rated tire. And depending on what someone is carrying in their truck it may be sitting lower than another identical truck leaving less fender clearance.

Most of the time a 255/85/16 will fit with no modifications. You may get some slight rubbing at full steering lock, but usually not enough to worry about. The disadvantages of that size is cost and limited options. You will also see some loss of power and fuel mileage. You will have to go with an E rated tire.

A 265/75/16 will almost never have any issues on a stock truck. No measurable loss of performance or fuel mileage in my experience. They tend to cost less with many more options. They are the biggest non-LT tire available on 16" wheels. That is my personal choice. They fit, and look good on a stock truck, but still look good with a small lift. To go any bigger means significantly more money and/or modifications to make them fit for very little gain in ground clearance. And you'll see a drop in performance as well as fuel mileage if you go any bigger.

 

I have 265 75 R16 on -6 offset fuels with a 3rd gen suspension and they fill up the wheel wells pretty well. no rubbing except that small aerodynamic flap in the front. I removed it, no issues.
