I'm running 35.12.50/15 falken rocky mountain ats the saleman said to run all 4@45 psi does that sound right?

 

What is the maximum PSI stamped on the sidewall?

If it is 44 or 45 PSI, no. Thats not what you're supposed to use, like many salesman say... its the MAX. My current tires are rated at 44 PSI, and I run 36-38. Anymore and you will wear unevenly and cause problems with the tires well before they are due for replacement.

 

35 max cold psi that's what made me wonder

 

35??? Thats a bit low. Maybe because they're 15 inchers...

I'd do no more than that. Probably 32-ish and see how they wear. If you start seeing excessive wear on the outside of the tread, give them more air. If you see them having excessive wear on the inside of the tread, reduce the pressure even more.

 

35 psi??? They should be LT tires which should be max 60 psi and 45 psi should be good. But if they do say 35 then run them at 35 psi. Our trucks are heavy enough to keep full contact on the street so you shouldnt worry about un even wear.

 

If put what the tire recommends to put in.

 

Sorry for being a little off topic but will a pair of 33/1250 tires fit under my 95 Dakota with minor mods? Mods as in turning torsion bars or bigger shocks

 

35 psi would be a load range B tire, which seems lightweight for a truck.
but don't exceed max pressure stamped on the sidewall.

if 35 is the max, i'd run that.

 

no my old 98 only fit 32x11.5 with rubbing on frame and new t-bar keys. my upper control arms also hit the bumpstops. the whole ifs is a joke and camber was never right. 31x10.5 is your max, if you still want decent suspension

 

There load range E ,I'm gonna call back tomorrow&see what they say.
