mixed tires

[cozadlance2]

k - i have gotten nice used 245/75/r16 rvt radials on the back axle. the front has m+s 245/75/r16s. Is this o.k? what is m+s? for that matter, what is rvt? thx.

[fordman]

m&s is mud and snow tire tread. i am going to guess that RVT stands for radial versitle tire. i dont know though.

[FORDification]

As long as all four are the same type (radial, bias, etc.) and the two fronts match and the two rears match, you're fine.

[cozadlance2]

folks here think rvt is rough varied terrain. google is no help.

[FORDification]

Are the 'RVT' tires made by Bridgestone? If so, it's part of the tire model name. Bridgestone makes a Dueler RVT, which would likely stand for 'RV/Truck'.

so, in a related Q: if I put bigger tires on the back than the front, this means I cannot rotate them, correct? I request an explaination of the real effects this has, not rotating tires. can i get away with just swapping side-to-side? I am trying to get over this childish desire to have huge tires on the back of a tired old 360 stock engine having truck. It isn't working, so I guess it is time to consider a savings account to bump the old girl up to a 390 made out of the 360.

If you want to run Bigger tires on the back go for it. Non rotating properly just means you will not get as many miles out of them. If the Truck is not your daily the tires will last a good while without rotating. I stay with the same size all around to allow for rotating and longer tire life. But to each their own. Besides what do I know? I'm just an Old F--t thats been around a few blocks. JMO

[robwymer]

Put whatever size on the back you like. Chances are with these old rides you'll burn through the fronts much faster than the rears. And like Mancar was saying, the rears will probably dry rot before they ever need replacing, especially if it's not your daily driver.

[cozadlance2]

well, mancar is a hero to me, after all he is dealing with. b.t.w. mancar, as important as a truck is, i feel as best a young-un (39) like myself can -- your pain. saw your post. much sorrow for her. I a sorry and wish my best. If same size is the vote of old farts, as you indicate, i shall follow the advice of my elders. best hopes for you two. thanks again for all the help.

I managed a tire store for a while. I learned a few things about tires.

Always put the larger tires on the back.

Your truck was designed with the same size tires in mind. It will drive and handle better with four equal tires. This mean it will be safer.

Swapping tires side to side will have little to no effect on the wear pattern.
The fronts wear on the edges cause they turn and steer the truck. The fronts will have a rounded look across the tread.
The rears wear in the center more and will have a flatter look across the tread.
Rotating front to rear will help offset this wear pattern. Rotating tires will help them to wear more even and ultimately last longer.

If you really want an education on tires, go TireRack.com. They one of the best tire write-up pages I have ever seen.

I've got 11.5 x 16.5 on my F250. I'm using the CS rims. It looks good, full like it should. Yes I can go taller, but I don't want to. And no, I don't know how much taller I could go.

[Mancar1]

I have enough trouble planting my backside on the seat without taller tires.

[cozadlance2]

Thanks folks. So many mods to do. So little patience. I would like it if my truck could morph into what I dream of but I would miss out on the learning. I so nearly gave up on this truck b4 I found fordification.com.
