Biggest tire on stock boss

[SteelBoss6.2]

wondering what tire sizes you guys are getting away with without additional lift! I'm wanting to stuff 305 65s on my stock wheels.

I’ve got 295/70R18 Falken Wildpeak AT3W tires on my 18-inch Trail Boss wheels. Just a tiny bit of rub on the mud flap occasionally when reversing with steering near full lock. I don’t have any lift or levelling kit, just factory Trail Boss suspension.

Here is a full pic for comparison:

Damn it looks good man. Wondering if the 305s will rub more or less. Theyre not as tall as yours but mucho wider

 

[SteelBoss6.2]

only one way to find out!

Update: I just trimmed the mud flap, removed the bracket behind the fender liner and then zip-tied the liner back to make more room in the wheel well. There’s lots of room now. Might try some 1.5” BORA wheel spacers for a wider stance...

Right on. Ill prob have to do near the same with the 305s.

I put Toyo 195/70's on mine. So, 34X11.5 roughly. I had to remove the mud flaps when I added Bushwacker fender flares. When I added the tires I had to remove the mudflap brackets and add 2" wheel offsets. When that was done I had no tire rub. Before the spacers It rubbed bad. Hell of a racket. I've read on the GM forums that you could put 195/70 without any rubbing. Anyone who says that is wrong.

195/70/18 or 295/70/18?

Ahhh good catch! 295’s they are

Can you post some pics of your tire/wheel set up? I’m curious what the 2-inch spacers look like with that tire size. I’ve got the same size tires on factory wheels and will be adding 1.5-inch BORA wheel spacers whenever they come in the mail.

Yup, I'll get some up. It may be tomorrow but I'm on it. I'm using factory wheels. There was no shaving needed either. Once the mudflap brackets were removed a self driller pushed the fender liner back enough. The 2" spacer made it look much better.

Yeah thats a tall tire, thats why I was thinkin 305 65s...they are 33x12. Hopefully no rub and I like the wider tires

those are some meaty ass tires fella! Alot more room without the mudflaps?

 

[seb5]

Yup, when I put the fender flares on I had to remove the mud flaps anyway. The real room was made by removing the mudflap bracket. I still hads to put on 2" spacers, which really made it look like it should have anyway. I'm happy with it now. The white truck with the large fender flares and original tires looked like a 250 lb. man with size 7 shoes!

Nice truck! How much do you think the tires stick out without the fenders on?

 

[seb5]

They're still inside the fender flares but without I'd say 2 inches or so. Mostly because of the 2" offsets I put on.

You nailed it on the comparison. I know it was done for mpg but man are they undersized for the size of the truck. They look like they belong on a pathfinder or tacoma!

I got the 1.5 inch BORA spacers yesterday and installed them on the Trail Boss. The 295/70R18 Falken Wildpeaks aren’t rubbing since I already trimmed the front mud flaps and removed the fender liner brackets. It has a nice stance now and reminds me of the Colorado ZR2 that I traded in. The photos don’t really do it justice, but I like it so much that I’m not even going to bother lifting it in the future. It’s got just the right amount of lift and stance for my liking. Hope this helps.
