Discount Tire,

First, thank you for all your bring to the table here.

Secondly, I have a question. I have a 2015 Tundra double cab 4x4 (no fender flares) with the Lowrange Offroad 3/1 leveling kit. I'm looking at 20x9 rims with a +12 offset. How far will that stick out the side of the truck? Will it look too wide? Also, what size tire do you recommend?

Thanks!!

Discount Tire, first off thanks for the thread. Ok so I have a 2014 Tundra limited 4x4 CM. I’m going to be installing a Toytec Boss 3 in life w/ 1.5 in shackles. I have my heart set on Fuel Contra D615 20x9. There are 2 offsets 0 and +20. Thinking +20 is better. Can I fit Toyo AT2 on it in size LT285/60r/20 says they are 33.5 tall and 11.5 wide?

Looking for quick confirmation so i dont get the wrong size. From what ive read i think these will fit without any modifications. Could someone please confirm this?

2018 Tundra Platinum

Tire size is stock, but the rims will make them stick out ~1.75" more than stock. You could have plastic rub when compressed and turning.

Every truck is different because alignment adjustments move the wheel fore-aft.

Wheels with +35 to +50mm offset are the sweet spot for fitting bigger tires on a Tundra and maximizing clearance.

Have you thought about bigger tires? Tundras look a lot better...

Yes i have but you cannot lift a 2018 Tundra without it messing with the safety stuff TSS. Maybe you can but i dont want to fight with my dealer for warranty issues down the road.

I don't have a lift, and my tires are bigger than typical 35s. I cannot make the tire bottom out on anything vertically. Contrary to popular belief, lifting the front is unnecessary unless you get >35s, and doesn't even reduce the trimming you need to do if you wish to avoid rub when hitting bumps. In other words you need to trim regardless, but the lift is optional. I'm talking about the strut-lifts. If you get >5" drop-bracket lift, that would give you some extra clearance.

You must clear the upper control arm; that's why you need a bit less than the stock offset (which is +60mm) if you wish to fit wider tires. Otherwise the more offset the better for clearance. The outside edge of a bigger tire rubs on the fore-aft parts of the wheelwell when you turn. Besides the plastic liner, you may also contact the skid plate at the inner front (easy fix), and the body mount at the rear of the well. IMO the body mount is easy too (a few minutes with an angle grinder) but a lot of people like to weld in a plate to close off the hole, and that can cost some money ($200 or so).

If you could find some wheels you like in +35 offset, the 305/65r18 or 34x12.5 KO2s would fit fine with only minor mods (no body mount rub).

Thanks rruff, I will look into these options for sure. Appreciate the details you provided now I’m aware of things I never thought of.

I just cant find any wheels i like with >35+ offset so im likely going to stay with the deegan 38s. Now im debating tire size but i think im going with 285/65/18 although i would do 275/70/18 since they are much cheaper and around the same size. What ive read its not a good idea to run these on a 18x9 wheel.
