The SKINNY on skinny tires

Correct. 255/75/17. Specs say 31.7”

 

Interesting skinny tire from Cooper. Skinny is less popular than getting 1 size up. With the Coopers you don't gain much height going for a skinny. I was looking for a little more than 30.7" in a tire trying to get to 32.x without rubbing and cutting on stock suspension. Is it not the main reason to get skinny tires in the first place? Size, Weight and Load.

 

So I’ve run 2 sets of 265/75/16s and just put on 255/75/17. They are maybe a few tenths of an inch taller and with the lower profile sidewall I expected them to look smaller. To my surprise I think the 1/2” narrower actually makes them look bigger.

Compared to a 265 they are lighter load and lighter weight. Cooper says 55 lbs but all 4 tires weighed in at 52 lbs. And they were about $15 a tire cheaper.

If you’re staying with stock suspension, tire width and wheel offset are going to make or brake you.

 

255/85r16 gets you +3 with nearly identical width

 

I picked up a full size spare 255/85/16 to replace the stock one with. does anyone know if the spare rim had the same offset as the Offroads rim? I’m just wondering in the event I have to use it if I’m going to run into any issues such as rubbing which I don’t now. TIA

 

You can ask Jeff Lange in the 2020 parts thread...

Hold a strait edge on the backside from m side to side then measure from the inside of the to the backseat de road f the center of the wheel if both are the same you should be good

 

Running 265/70/17 Wildpeaks and when I had them installed they are rubbing the UCA’s near full lock. I have OME 885’s on the front and Dakars on the back.

previous tires were ok.... wondering if a skinnier tire will help. Seems it would? Are the Wildpeaks just more ‘blocky’ ?

Previous tires were not that aggressive

 

What size are your wheels, width and offset?

 

Sorry, stock wheels on my 2015 Sport

i did have spacers for a bit and that solved it but i hated the look and feel.

 

I think that might be 17x7.5" +30mm

265/70R17 SL tires are 31.7" high and 10.8" wide (1.0"/2=.5" difference)
LT265/70R17 E tires are 31.9" high and 10.7" wide (.9"/2=.45" difference)

245/75R17 SL tires may not help 31.5" high and 9.8" wide

The spacers are an option or a lower offset wheel of +0 if +30mm is correct.

These wheels are 17x8.0" +0mm offset...

i get confused on this when looking at the tire comparison numbers. Seems an inch narrower tire ought to keep the tire away from the UCA

 

yes but centered on the rim so .5" each side.

 

That makes sense

 

Your spacers were 1.25"? If so that is -32mm offset difference, similar to having +0 offset wheels. I would think you would want more than .5" of clearance if you are rubbing on the UCA's. Depending on the wheel width you would want make a 0.75" (20mm) difference if you want to avoid using the wheel spacer. Wheels 17x8" +10 to +0 offset, wheel spacer or stock tire 265/65R17 are your choices.

 

I really like the look of your truck. I have a couple of specific questions about the wheels based on some feedback I received from the local shop. I recently had my truck leveled and lifted 2.5". My intention was/is to put the 17" TRD Pro wheels with 255/80r17's. However, the shop owner is telling me I shouldn't go with the TRD wheels as 7" is too narrow. He's saying 8" width should be my minimum.

So my questions are: Is 7" width too narrow for the tire size I'm wanting? Is the 4mm offset sufficient to avoid rubbing?

 

From my understanding, rubbing isn’t much of an issue until tires start getting to that 12” width. With the ~2” OME and skinny tires, no UCAs needed, and no rubbing.

Also, I think 6.5” - 8.5” wide is suitable for that size tire. Ref.

 

Thanks. Forgive my naivety, but what is UCA? What about the "... 7 inches is too narrow" comment?

Edit: Upper Control Arms... got it.

 

When talking 33's the tire shop is thinking 285's should be on an 8" wide rim but you are wanting 255's approved rim width is 6.5" to 8.5". Just check the tire specs for the tire you want to use.

 

Looks great! That's a very sound setup! Welcome to the forum
