20" x 10" +13mm wheels need help choosing tire size

finn5033 · October 19, 2022

Hello all, I have been running my 2021 3500 on the stock black 18" wheels with some 295/70/18 wilkpeaks for about a year now. As usual I am bored with it so I wanted to get different wheels. I want to go with 20" wheels and I wanted something with a little more lip and that sits more flush. I found a few brands now that are making 20x10 wheels with a positive offset and found some Weld off-road wheels that were on sale for by 2 get 2 free so grabbed them. Just trying to decide on tires now. I usually buy my tires from Discount tire because I always have and have never had a bad experience. The manager at my store is telling me that if I use that wheel with a 285/65/20 that it will rub at stock height. So obviously a 295/65/20 would even worse. After exhaustive internet searching It seems plenty of people are running something similar and not having that problem. Doing the math with that wheel a 285/65/20 is going to stick out 1" farther than my current set up and the 295/65/20 is going to stick out 1 1/4" farther than my current set up. Both would put the outside of my tire right about flush with the fenders. If anyone is running something similar can you confirm or deny I'll have issues with this if I don't raise the front up some? My other issue is wondering if the 285 tire will look ok on a 10" wide wheel. The more I think about it I may just go with the 295 so there is a little more width on that wheel. Any help is greatly appreciated. Sadly I don't have pictures of my truck with the current stock wheels and the wildpeaks. I attached a picture of the wheels I bought.

sorry I don't have any input on tire size; I'm going to follow for pics after you decide and get them installed. Look forward to seeing the truck after mounted!

Have you looked into adding a leveling kit? I'm sure that'd give you plenty of clearance since you're not going with anything crazy wide.

I don’t want to level it. It’s used mostly to tow our RV fish house year round and it squats the rear over 2 inches. I actually have been flashed quite a bit the couple times I’ve towed in the dark. I need to put some timbrens or sumo springs in.

I’ve also now considered sticking with 18’s. I’m currently running 295/70/18 Wild peak at3w’s on my stock black 18’s that only have about 7k miles on them. All the tires I want in the 295/65/20 are $400 a piece or more. So now I’m thinking about getting some 18x9 wheels around a 0 offset. That way I don’t have to buy tires or pressure sensors. I really just want that wider stance and this would accomplish that

So last night I went out and took some measurements on my stock wheels with the 295/70/18 Wild peaks. Using a 4’ level it turns out the side wall of my tire is nearly flush maybe 1/4” tucked in from the fender. So this morning I decided to order up some Fuel Blitz wheels in 18x9 +20mm offset in gloss black. This will actually move everything out almost an inch. So I’ll have just a little poke from the fenders which is what I want. But it still keeps the main part of the tread under the fender. Plus the wheel being an inch wider will square up the tire some more which is also what I wanted. I’ll come back and post some before and after pictures. Plus being able to reuse the tires and the pressure sensors is saving me a lot of money.

Are you planning to sell your OEM rims? Been trying to find a set of black 18" rims but most take offs seem to be 20s

was really curious to see the Welds mounted, but the Fuels look good too. Can't wait to see them mounted up.

Well the title of this thread certainly doesn’t apply anymore but I figure I’ll keep updating. Turns out the Fuel Blitz gloss black 18x9 are on national back order in the +20 offset and the +1 offset. I checked multiple places and they all said the same. 60-90 day’s minimum but could be much longer. I had initially wanted to go up to 20’s and since these wheels were available in 20x9 +20 offset I ordered them.

I’m also very glad I never mounted tires on the weld off-road 20x10’s I initially ordered. While at discount tire the manager showed me a wheel offset calculator that they use to help people choose wheels. Going from a 8” wide wheel and +44 offset to a 20x10 +13 offset would have moved the outside edge of the wheel about 2-1/4” farther out. And that’s just the wheel it doesn’t include how much farther the side of the tire sticks out. Being as currently the outside edge of my tire is almost flush with the fender I would have been sticking out likely well over 2”.

long story short I have the Fuel wheels on order and ordered a set of the new Nokian Outpost A/Ts in a 285/65/20. I’ll come back with pictures when I get the new set on.

I ordered Fuel covert 18x9+20 with Nitto Recon tires 295/70R18 .
based on my math calculations. I should end up really flush with my fenders or very close to it.
Which is what I am after. Custom Wheel offsets has a great gallery for seeing what different combinations look like.
May not find the exact wheel tire combo your wanting but you can find sizes and offsets like;y similar to what your looking for in similar size and offset with similar size tires.

I searched their gallery way too much plus other sites as well trying to figure out what I wanted. It was very helpful though. I originally wanted something a little more aggressive and ended up more tame. I wanted to go with a 295/65/20 tire but ended up with 285/65/20 Nokian outpost A/T tires. I went this route because discount tire gives you 30 days to try tires and if you don’t like them for any reason you can return them. They aren’t quite the look I wanted but they are smooth and quiet. I had 295/70/18 Falken Wild Peak A/T3W on my stock wheels and I’m shocked how much louder and rougher the ride was with them. So now I think I’ll just stick with the Nokian because I’m so happy with the ride. I wanted to try the Recon Grapplers but they aren’t 3peak snow rated and I do a lot of ice fishing so that was a deal breaker. Then I wanted to go with the Toyo A/T3 but I got the Nokians for $100 each cheaper so I decided to give them a try.

Turns out Finn and I have identical trucks, with the exception of a 2500 vs. a 3500. Anyway, here’s the Weld wheels with Toyo 35x11.50. Not sure why my picture is upside down, but thought I’d share what they look like. I gave the stock keys 5 turns, I might turn them down one and then get my alignment.

I just put on the Icon Rebound 20" x 9" Plus 12 with Nitto 325 x12.5 x 20, Truck has the Snow Plow Prep Camper Package,

slight rub on front mud flap at full lock in reverse, still at stock factory height

Looks good. I ended up turning my keys back down 1.5 turns, so I ended at 3.5. This gave me a little bit of rake and minimal rubbing. It hits the felt liner at full lock but clears the mud flaps with ease. It’s currently at the shop for an alignment, I’m interested to see how far off it was.
