Tire size choice for 07 Yukon (275/65 or 305/55)

[NGAneer]

Okay, searched and didn't find much in terms of results. I'm looking for 275/65r20 on a leveled NNBS Yukon/Tahoe. I've long considered 305/55 and still will but in terms of price, I feel like I might be able to get off cheaper with 275/65 and I need the back up plan. Looking at aggressive all terrains (Duratrac, KO2, Cooper S/T Maxx, Toyo AT2, etc.) Pics of a leveled setup with 275/65r20 or similar would be a big help. Truck pic below.

I'm leveled with 275/60/20 (33x11). I like it but I want wider tires. 275/65/20 would look goofy and might have firment issues. If I had to do it again I would go 305/55/20 or 295/55/20

If running stock rims 305 on a level will rub the sway bar. The 275/65 are tall but skinny however weigh a lot more and need higher air pressure to carry same load of stock 275/55. Makes the ride harsh. I would go with a 295/55 or 275/60 for the choice.

There's no way you're going to fit a 275/65 with just a level. I have 275/60's and they only clear by a cunthair

mine clear fine

If you do a 1.5" leveling kit to bring the front up level with the rear, it's a tight fit for 275/60's which is a 33" tire. If you do the 2.5" front and 1" rear they will fit fine, and you might be able to tuck the 275/65's, but it's going to be tight since it's a 34" tire. I've honestly never heard of anyone running that setup though

If I did a CCM 2.5/1 and wanted to do 305/55/20's what offset wheel would I need to avoid rubbing the sway bar?

This is the look that I am going for but with different wheels/tires. It seems they made it work with a 20x9 +1:

The 305/55R20 is a big tire to fit on a level kit. They really measure out to be 33.5" or you can search to find one that is smaller closer to 33". You could do a 33x12.50R20 which measures 32.7-33". I would still say go with a 295/55R20 which is 33x12. Those are a lot easier to fit. Still require bunch or trimming and fender modding. Need to trim the inner bumper brace behind front fender liner and do the small norcal mod.

As far as rims as long as its not a 305 on factory wheels it will clear. For example 295/55 on stocks no issues on sway bar. For aftermarket wheels you need to stay above 20x9 +25 and below 20x14 -76. Flush to fender or +1/2" out wheels are 20x9 +0 or as close to that offset. Stock wheels to flush fender is 20x9 +12 to +25. Big offset is 20x10 to 20x14 ranging from -24 to -76, no way will these fit on a level without major trimming.

Thanks for the Advice. I think I might just try a 295/55/20 on my stock wheels for now. There doesn't seem to be very many tire choices in that size though. The only ones Im finding are Nitto Trail Grappler, Cooper STT Pro or Toyo Open Country A/t or M/t.

 

[Jonah52]

all the pricey ones lol

 

[JT 07LTZ]

No kidding. $1500 and up a set is ridiculous! Especially for only a little bigger than stock. Those Toyos look so good though!

 

[01Konvict]

That's why I said 275/60R20 to begin with. Class C tire instead of those heavy E tires. For those that don't know it's 6 ply to 10 ply steel belts. Weight goes up about 20 lbs per tire which kill mpg. But everyone wants that big tire look

Would doing a Zone 2" body lift on top of the CCM be worth it? Do you know what size tires I would be able to fit?

I didn't even think about how much more weight those extra ply tires would add. MPG is bad enough with my 93 Tune. Looks like a set of 275/60/20s are in my future.

 

[01Konvict]

Doing the 2" body lift plus 2" strut kit will allow up to a 34" on stock rims but have to be 295 width or less. Still those 295 and up are class E being heavy plus cost double. It's all possible but doing a combo kit to clear heavy 34s makes you decide is it worth that look...

 

[JT 07LTZ]

Well you have definitely helped me put the cost into perspective. I am going to just stick with the CCM and 275/60/20's. Either Cooper Zeons, Goodyear Duratracs, or BF Goodrich KO2. Any recommendations?

 

[01Konvict]

The CCM kit is good and if you ever want to go bigger then you can add the zone 2" BL. As far as those specific tire choices I would rate them as following: Coopers are good inexpensive tire with nice looking tread, have used these tires and wear was pretty good. Duratracs are the most aggressive and quiet for tread design, wear is good. KO2 have great sidewall design but often the smallest actual tire size in width/height. Take a look at the Toyo AT2 as its a great tire. What exact style look do you want?

 

[Jonah52]

Keep in mind too mud terrains are super heavy. My buddy has 35x1250x17 on his cummins and they are 98 pounds a piece. My 275/60/20 look good, a little narrow, but are $800 new lol not $1500.

Thats probably the best course of action. I do like the Toyo AT2. I think it's between them and the Cooper Zeons. The Duratracs seem to be a crapshoot between good and bad reviews on wear/roadnoise. I really like the more aggressive look of Duratracs or a M/T but I don't want to give up road manners or have a bunch of noise. I do 80%+ on-road/highway driving.
