On my 2007 Dually. Can I fit 285/70/17 Tires on the back without them touching? or do i have you run a spacer and what size? Thanks for any help

 

Well, what are you running now? 285's are about 11.25" wide, and 245's are about 9 5/8" wide. If you have 1.5" between the tires, and you go from 245 to 285 they will touch.

 

Can I get away with running a quarter inch spacer between the wheels provided there is enough lug to do so? I saw a truck like mine at tractor supply the other day with 285s they were really close. I would say 1/2 inch at most and is that to close?

 

I would say that is to close. Especially under a heavy load.

 

Nah, run 'em!! I had a dually that was close, and the tires touched when I had it loaded with stone and cement. I never had a problem with those tires. They turn at the same speed, so there's no rubbing.... They just kiss when they squish.

I ran my dually for many years like that.

 

I'm running 285/70/17 bfg all terrains on my 06, 1/4 " spacer, no rubbing, but I dont really load the bed or tongue very heavy..

 

Do you know is there enough lug with a half inch spacer?

 

^^^^^^^^^^ No, I'm pretty sure not.^^^^^^^^^^

 

Bad advice. He just told you that the tires TOUCHED when loaded but he still wants you to run them anyways. Use your head & ignore this advice.

This is a disasterous situation waiting to cause major greif. Do NOT run any tire width that rubs under load under ANY circumstances. If you want or need bigger tires run a spacer to keep then apart.

 

So why would this be a problem? Why is it dangerous? I did it for years, never a problem at all. But I suppose you are a tire expert and can tell me exactly why dual wheels cannot touch on the bottom near the contact patch.

They are not rubbing. They squish and kiss for a brief instant.

I would NEVER run a spacer. Now THAT is asking for trouble. That rim needs to seat on the hub. When you are on uneven pavement ALL the load can be on that outer wheel. It better be on that hub or the lugs are supposrting everything.

 

If the tires touching was not a problem ask yourself why in the history of trucks no vehicle has EVER been made where the tires touch.

Just because you have not had a problem with it does not mean it is not a problem waiting to happen. Consider yourself lucky....albeit irresponsible.

 

Tires touching will push more snow, push more mud. Not clean as well. That's why they don't build them that way.

There's always a couple that think there's only ONE WAY anything can be done, and the manufacturer ALWAYS has the BEST parts yada yada yada....

Whatever. If you want to run little baby tires olds, you go for it, but don't spew false information that it is dangerous and irresponsible to have dually's touch. You've never seen a problem with it. You've never heard of a problem caused by it. You just want to make noise.

 

Just the facts, fellas. Don't turn this into a peeing match. If you don't agree, just state it and leave it at that.

Thanks.

Like I said, no peeing match here. Take a week to cool off.

Anyone else?
