Topic: Wheel Spacers

Posted By: Chief 2 on 01/16/12 05:09am

The rear tire spacing on my 2005 Chevy 3500 dually is just not enough when I have the tc loaded. There are may times when the rear tires are rubbing and I certainly am not comfortable with that. Is there anyone using wheel spacers and can you comment on how they have helped, where you purchased and anything else that may be helpful. Thanks!

Stock sized 16's. Thanks for the link.

Are your tires fully inflated? I can't believe that stock sized tires would touch each other when loaded (or even being a little overloaded).

These are probably the best spacers out there , don't go cheap .click

GM duallys have the least space between wheels compared to Ford and Dodge . I think I am going this route also . I had a set of 2" spacers on my old suburban for over a 100k with no trouble and they were not hub centric .

Running 80 psi. Even unloaded the tires sit close. My buddys Dodge has a bunch of room between his tires even loaded with the same model tc.

Chief , are you sure you don't have 235's and not 215's ?

GM spec is for max tire width of 9.1 on stock rims

Michelin 215/85/16 is 8.5 stock size
235/85/16 is 9.3
225/70/16 is 8.8


There is slight variance in brands.

I am running 235's and they barely touch at full load .


Posted By: Chief 2 on 01/16/12 03:22pm

Just double checked. 215/85 R 16 load range E. That is what is on the door and on the truck.


Posted By: Chief 2 on 01/16/12 11:44am

Michelin load range E. The Goodyears that were on there before did the same thing.

I suppose the upside is that it makes it harder to pick up a rock between the duals. I can put my fist between my tires but that also means the potential of anything else about that size lodging there when I get off the pavement. I am always checking before I get back on the pavement so I don't throw a rock at my truck or camper at high speed. So lucky you not having that concern but it is odd that GM would make it that close so it touches when it gets a load it. Good luck, hope you find what you need.

Chief 2, just for kicks, what exact size tires do you have?

A 2005 should have 215-85R16.

Posted By: Chief 2 on 01/16/12 08:56am

That is the size!

I actually spoke with Fred yesterday. The old guy called me from Ca on a Sunday morning. He has a good product, but $320 for the pair. You get what you pay for though!

It's the opposite. The wider rims will allow the tires to be wider overall. Wider tires spaced the same distance apart center to center as a narrower tire, the wider tires will be closer together.

To the best of my knowledge

The 17x6.5 wheels didn't come out until the NBS ( 2007 )
From 00 to 07 it was 16 x 6.5
Prior to 00 it was 16 x 6.0

Ford has an option for a 5.35 offset wheel 6 x 16 , to fit 235/85/16 tires
Good point on the diameter. If the width is the same 6.5" either way, 16" or 17", the result would be the same, provided the offset of both wheels are 5.00". I'd have to check on the offset for the 16" wheels.

Yes, F350 cab/chassis dually has the 5.35" offset wheels. It's stock tire size is 235, versus the 215 stock tire size for the F350 dually pickups of the same era.

3/8 gives me just enough separation. I didn't want to go more than that because I didn't want to have to change my lug bolts to longer ones.

Are the rims stock? Awful odd that the stock tires would rub that much, especially with something as narrow as a 215, especially with the sizes on the tires being confirmed as 215/85s.


I have to agree , never heard of or seen stock tires with stock rims touching , and I have checked many before I up-sized tires.

If the 3/8 spacers are not hub centric you may have a had time centering the outer wheel , the studs do not align it .


Posted By: BudWizer on 01/16/12 05:40pm

I had the same problem with my 06 Chevy when I put new Michelins on it. They were 215-85 16E Michelin LTX M/S 2. They just seemed too close for comfort when the camper was on the truck so I bought some 3/8" spacers on ebay. They were not expensive and only being 3/8" wide, they did not require longer studs for the lug nuts.
