I plan to order a set of tires and a leveling kit for my 1794 Tundra pretty soon. I believe the factory wheels are 20x8. I don't want to replace the factory wheels or add wheel spacers. I will be installing a leveling kit at the same time....so will 305 55r20 nitro terra grapplers or ridge grapplers fit?

305/55R-20 sized tires are most likely going to rub the UCA with the factory wheels due to the high wheel offset. 285/60R-20 sized tires may be a better solution if you want to stick with the O.E. wheels, or you could swap to an aftermarket wheel that has a lower offset.

My dealer puts 305/55/20 Nittos on the trucks they upgrade and then overcharge for the upgrades.
I stick my finger between the tire and the UCA.

Those stock TSS wheels are 20X9 with 55+ offset.

I agree with Discount Tire, it is a bit too close..

I agree that looks close. I guess the biggest question at this point is what the offset is on my wheels. I've searched and haven't found it yet. If 55 barely clears and I have 60 I'll know it won't work for sure. If mine are 50 it might be tempting. Lol

I can buy spacers if I have to... I just like wide tires but don't want to go crazy modding this truck. I may end up with 295's to keep it simple.

Our records indicate the offset is +60mm, but you can confirm this by looking on the backside of one wheel. The offset will be stamped somewhere next to the letters ET.

8" rim is below the recommended width, besides the UCA clearance issue.

I'd go with 295/60s.

I'm needing new tires soon.
I'm going to buy Toyo Open Country AT from my local Discount Tire.

I currently have stock 285/55/20 BFG KOs.
I was going to get the Toyos in 295/55/20, but after reading this thread, I think 295/60/20 is going to be the way to go.
I have a 2.5 lift in front and 1 lift in the rear/

I think 295/60/20 is going to be the way to go.

They are ~34" and if you don't mind a little plastic modding for clearance they'll be fine.

THIS. The minimum safe rim width for 305/55R-20 sized tires is 8.5-inches.

My apologies for not catching this earlier, bigbair2002.

 

[bigbair2002]

Against the recommendations here, I decided to go with the 305/55r20 on my stock 20x8 wheels. I just cannot see the 8" vs 8.5" rim width making a huge difference...and I've done worse in the past with 37x14 on 18x9 wheels.

I ordered a 3" leveling kit for the front, add a leaf for the rear, and 3/4" bora wheel spacers all the way around. I'll try to post some pics when I get everything in and put together.

I mounted 35x12.50 on my stuck 18x8 rims on my 2014 tundra with a 3/1 leveling kit only modifications I had to do to clear them was trim like an inch off the skid plate and remove the front mud flaps I clear them no problem now zero rubbing and I didn’t need wheel spacers

 

[bigbair2002]

I've had the leveling kit, tires and wheel spacers on for almost a month now and really like it.

I installed the spacers and tires first and the tires would only rub occasionally while backing up- and they still do sometimes with the leveling kit. So the leveling kit was not needed for the tires but I like it.

I believe the tires would have cleared the UCA without the spacers because with 3/4" spacers I have about 1" of clearance. I know 1/4" or less would be close, but I think it could work. I am still glad I went with the spacers because I really like the stance.

I didn't find a lot of reviews on the Cooper Discoverer AT/W tires but they have been really impressive in the snow so far even with the extra width. No idea how well they will actually last but so far I would recommend them at least as a winter tire.
