13.50's or 15.50's?
 
Does anyone have any experience with 38" Toyo Open Country M/T's? I really want to go up soon and was planning on 38's but not sure what width..I'm currently running my BMF's which are 20X10's..I think both tire sizes will work for the rim width but was just wondering if anyone had any experience with either size. Pics would be great!

Thanks!
Austin

I think you would be fine with the 13.50 since you are lifted right?

Roushdemon ran 15.5 38" tires on those XDs 20x10 and they looked AWESOME!!! really beefy!

I've got 40x15.5x20 and love them! There on fuel octane black where's that are 20x12 with a -46 offset. Stick out real nice and has a very very wide stance. Love the look and rides great

Re: 13.50's or 15.50's?
 
It's my understanding that 15.5's can put more stress on brakes, suspension, and transmission as there is more tire surface touching the ground, equating to more resistance. I have 38X13.5X20's on mine, and they have been great. Also, keep in mind that no matter what tire width you run, the real key to prevent rubbing is the correct offset of the wheels.

When I spoke with a VERY respectable shop here in Orlando, they made it very clear that 40" tall tires were too big for Chevy based trucks without substantial upgrades, and 15" wide tires would put a lot of stress on certain components.

Re: 13.50's or 15.50's?
 
I also heard that and thought about asking but didn't know for sure..So say I went with the 15.50's, I would need to upgrade several steering parts as well?

charles06 09-13-2011 09:15 PM

Re: 13.50's or 15.50's?
 
You should upgrade those parts even if your truck is basically stock. Stock tie rods are known for going bad, and there are some excellent alternatives. And some of the steering braces are highly recommended, as well. Not only will they last longer, but they'll help hold alignments. Considering some of these parts are cheaper than an alignment, it's a no-brainer.

adamw89_2000 09-13-2011 10:01 PM

Re: 13.50's or 15.50's?
 
simply put.. these gm trucks have weak steering componets... if you do any changes at al to bigger wheels and tires most professionals would reccomend upgrading these parts anyways. so with that being saids thats why i went with the 40x15.5x20. its a whole new look over the 38x13x20 in my opinion

Re: 13.50's or 15.50's?
 
I've been in the same boat as some of you guys in regards to tire size. The reasons I stuck with 38's were the advice I got from my shop, carrying a spare, and being able to match up gears, programmers, etc. With 4.88 gearing, a programmer, and other mods, I'm able to cruise all day long at 75mph, and don't find my truck constantly downshifting at the slightest hill. In fact, at 70mph on a hill, I can easily still accelerate up to 75mph or greater. Prior to the gears, my truck would downshift, and I'm afraid going with 40's would cause this again, even with the 4.88's.

Another benefit I've found by staying with 38's is that no programmers, custom tunes maybe, go up to 40" tire sizes. They top out at 38's. With the gears and programmer, my speedo is corrected. I feel it keeps the truck more drivable. But, please keep in mind, I'm saying this without having driven an H2 with 40's.

I will say, however, that all the pictures with 40" tires is really tempting me. They DO look awesome! Maybe after I get a third car...

Re: 13.50's or 15.50's?
 
I will say charles your truck would look absolutely insane with 40s! You definitely have the room for it..I was afraid I may not clear 40s if I went with a standard 6" lift. I was thinking about a 4" rancho plus my keys, giving me a huge lift while paying for a 4" lift. Course no lift for a hummer is cheap, they're ALL bad expensive. I could see where the truck would be more drivable with 38's versus 40s. I mean I could do 37s but I could clear 37's right now with just a truxxx lift. The 15.50s look really good in pictures, but I've never actually seen them in person. I've seen several 37X13.50 and those are big tires! I can't imagine the 15.50's! But all of this means nothing if I don't lift the truck, but it's been something I've wanted to do since I've had it. Do either of you guys have trouble driving it around town? Meaning is it too large to drive comfortably around town?
