    I have a chance to get a set of Badlands XD 20x10 from a Silverado. The tires are Goodyear Wrangler SR-A's 275/60/20. I'm guessing the bolt pattern is 6x5.5 because every other Chevy truck uses that standard except my '05 Trailblazer of course. So I was just wondering if these would work on my truck with adapters. It's stock and not raised. Thanks for the help.

    I also found another cheap set of wheels from a Suburban. 275/55r20 6 lug and again, I have no idea the bolt patter, but I'm guessing 6x6.5

    Firstly, the GMT360 and SSR use the same bolt pattern, no other vehicle has it. Any other wheels will have to run an adapter. The stock tyre diameter of our trucks is 29.5". With NO adapters, you can run 30.6" diameter, bigger than that you'll rub against the ball joint. You can do the math from there.

    Actually you cant do the math from there since he already stated with adapters....

    However neither will fit without significant cutting or a lift or both as they are 33 and 32 inch diameter tires.

    Thank you, that is exactly the answer I was looking for. straight and to the point.

    So what is the biggest / widest tire we can run on stock 17's? I think I read somewhere that it is 265.65.17. But if I put on 1.5" to 2" wheel spacers, would I be able to go with a bigger tire? I like the stock wheels, I just need to clean them up and touch up the black paint a little, but I think I'll stick with them and try to get bigger tires.

    265/65R17 or 30.6" diameter.

    Even with with spacers, that's the biggest I can fit on the stock wheel? And since I'm on about wheels and instead of making a new thread, I took a Brillo pad to my wheels today and it kind of dulled them up, like it stripped off the clear coat. Is there a way to bring back the shine? This is the wheel I have.

    You may very well have started to take off the clear coat, I dunno what would bring them back but I'm sure that one of the guys that detail their truck could answer. You may need to make a new post in a different thread...maybe the appearance one.

    In regards to widest tire you can run, in a post on ORTB it says you can run a 285/60R17 with no spacer, but I, personally, wouldn't feel comfortable putting 285's on our 7" wide rim.

    I know I keep beating this wheel thing, but would 07 Tahoe 255/75/20 wheels work with a 6x5 to 6x5.5 adapter?

    I stuffed a 275/70R18 (33x11) on mine, lifted/spacers/cutting required.

    so no 18's or 20's will fit? I keep coming across different wheels on Facebook sale sites, most are 6x5.5, but with 1.5" adapters I can probably get them to work. I'm just really bad at figuring out this tire size thing. I'm understanding that without a lift, the highest we can go is a 30.6. I just have to remember that. And thanks for your patience guys and no one said use the search box. I always use the search box when I have a question first. If I don't find the answer, I ask. Sometimes a little while after I search and don't find the answer, I type the search into Google and it brings me to a page here, LOL. I guess I just input the wrong search.

    18s or 20s are fine. both were stock wheels sizes. You just cant fit fullsize diameter tires. As you know you need to stay under the 30.6. If you google a tires size it will tell you the diameter in the specs typically.

    Alright Gentlemen, after doing hours worth or research, I've come to a final decision about what I'm going to do. I'm keeping the stock 17" wheels and I'm going to spray them flat black and body color the 5 spokes. I'm also going with 2" wheel spacers. I like the aggressive look when all 4 tires are sticking 2" outside of the tire well. And now, the final part is the tires, I'm not sure which ones to go with. I'm not doing any leveling or lifts, everything is staying stock.

    2 inch spacers wont set them two inches past fenders as they are not flush to begin with. You might get an inch out if that.

    You will need to do some plastic and maybe metal trimming for the 265 tire.

    you're right about the tires not sticking out 2", but it's enough to be noticeable and I still like it. I got my info from a thread on offroadtb about the tires. I've been browsing a lot over there. Lots of good info there too. But if it needs cut, I have no problem with that. This thread inspired me a lot. http://jd.offroadtb.com/modifications/#Tires

    by the way, did you mean it will need trimmed because the 265 is too wide or because the 70 is too high? I'm still learning this tire info.

    You really cant cherry pick one number or the other on a tire size. They work in concert. You also have to toss in the change in backspacing from the spacers and how it affects the tire swing as the suspension cycles. James kept his stuff tucked way in and narrow to run larger tires versus someone like me that runs wide stuff. Wider needs more cutting or lifting by far.

    Let's take your one tire size example, 265/70R17

    The first number is the tire width in milimeters
    The second number is the percentage of that width that makes the sidewall height
    The third number is wheel diameter in inches

    (Yep, we have mixed units for our tires!)

    So if you have a 245/70R17 tire and a 265/70R17 tire, the second tire is going to be both wider AND taller because 70% of 265 is more than 70% of 245.

    A 245/70R17 and a 265/65R17 are roughly the same height, for example.

    Something else to remember is the sidewall height is just from edge of wheel to the tread. Total tire height is twice that number, plus the wheel size.

    Instead of trying to do all the math manually (especially with mixed units), this website is very handy for running comparisons:

    https://tiresize.com/calculator/

    Just wait until you get into wheel sizes with width, backspacing, offset, etc - yep they have mixed units too :blinkhuh:

    so standard vs. larger. 245mm=9.65 and 265=10.43, making them an inch wider, but also including the 2" spacers.

    65mm=2.56 and 70=2.76 adds about 5.5" to the over all tire size

    How am I doing so far?

    No. 65 is a % and so is 70

    so it would be 65% or 70% of the first number and the first number is the width. so if the first number is 265mm which equals 10.43", then the height of the tire would be 65% which is 6.78" or 70% which is 7.30"? From top or bottom of rim to top or bottom of tire, it's the sidewall. And standard is 245mm which is 9.65" and the height would be 6.27" from top or bottom rim to the top or bottom of the tire.

    maybe this will help: 09 TB 4x4, 1.5" wheel spacers, no lift, on stock rims
    i run 265/65/18 (31.56" diam. per Disc. Tire calculator) in summer and
    265/70/17 (31.6") in winter.
    i have not done any plastic trimming or metal cutting.
    get a slight rub on inner fender wall on a turn , only if i hit a bump. usually wile backing out of driveway.
    and for an idea on how far the spacer bring the wheel/tire out, this is with 1.5" spacers.

    spacer stick out 001.jpg

    spacer stick out 002.jpg

    and another random question, thanks guys for all the help.

    In the tire specs if it says Measured Rim 8", does that mean that it will not fit on our 7" rim? I probably answered the question myself, but I wanted someone who knows the right answer to let me know. Thanks again.

    It is specs for that that rim when they measured, but they will also post a range of 7-9 for example that is ok to use, but will mildly change some measurements.

    That makes sense, thanks.

    How much work into cutting would it take to fit 32" tires on stock 17"s with a 2" spacer and no lift. I have a chance to get a set of 5 near new 255/75/17 BFG Mud Terrains that I would love to throw on.
