Tire wheel combo question

I’m sure y’all are tired of seeing these but, coming from building Hondas, this is all rocket science to me.

I have a 21 Tundra 4x4. Bought Eibach pro stage 2 something coilovers last year. Still haven’t installed. Now I want to buy tires/rims and this is where the confusion comes.

With the suspension at its highest point, I’d like a 17 or 18” wheel with a 35” tire without having to cut unless I absolutely have to.

I’m guessing I will need UCA’s. What size is my best option for this? I’ve searched and searched and still confused as hell hahaha

 

Offset is the only thing that matters. +25-35 is the sweet spot to clear the UCA and body mount.

 

This. 18" wheel, 285/75r18 is a great 35" tire for our trucks. might save you from having to purchase UCA's too.

 

for 35x1250s, you need UCAs and new wheels or spacers. Tires that tall and wide will hit UCA and lower offset wheels would require losing mudflaps and or wheel tub plastics massage, depending on offset, body mount chop. But there are tons of build details of trucks with 35s here so you can do it without much fuss.

I run same suspension, stock wheels and 285/75-18s, same height at 35s (34.8) but thinner. Work perfect on stock wheels and no UCA needed. I kept mudflaps and no trimming. I used this size specifically, for good height, less weight and better MPG. Truck actually performs better and gets better MPG than when I ran 33 inch Wildpeaks!

Azhauler is right on the offset for good fits on our trucks.

 

thank you, I was looking at the method 305’s 18’s with tan 0/5 offset. So the 25/6 is the better way? So damn glad I asked. Haven’t been on a forum since the Honda-tech days lol

 

0 offset pushes it all way out. To the point of paint damage on sides of truck. Some like the look but that offset usually has fitment challenges, trim, etc.
Here is a helpful tool to visualize different tires/rims offsets

 

When you list 0/5 and 25/6, what are the 5 and the 6 representing? The 0 and the 25 are indicative of offset, but the other numbers are confusing me…

But, I’ll echo what’s been said already. Look for a +25mm to +35mm offset if you want a good fit that doesn’t require a ton of trimming. Sounds like a ton of positive offset, but keep in mind that the OEM wheel offset is +60mm!

More often than not, your 17” wheel options will be 8.5” wide. The 18” options are typically 9” wide. You can do either one without issue.

If you want a standard 35 x 12.50, I’d be looking at 17” whees because you have so many tires to choose from. Many of these are available in a Load Range C.

I’m a huge fan of a slightly narrower tire and went with 285/75-18 (35 x 11.5-ish), but they’re pretty much only available in Load Range E…. It’s not a bad thing, I’m just putting it out there. I’ve been running LR-E tires on my Tundra for the last 80K miles without complaint, but some folks prefer the LR-C.

A 12.5 will be more work to make fit without rub, but it won’t be too hard. Recommend having your alignment adjusted with some more positive caster to push the tires forward, and you miiiiigghhhtt need to do a BMC. No matter what you choose, it’ll be great!
