i got new tires for my truck, P265/85/16 ( got em for free, brand new ), they are rated at 65 psi, when i first drove the truck, you felt every little bump in the road and the ride was terrible, i lowered them to 50 psi and now the truck bounces all over the road and the steering is sloppy....my original 2-ply tires rode beautiful...what can i do to help the ride? what air pressures suggested and will changing the shocks help? or do these tires just stink, average all terrain treads, no namers i think.....

 

barra..Since we don't know what kind of tire you went from too? Its probably a combination of a harder tire (ply) and shocks. I run 305/75/16- 10ply tires with 45psi in front 40psi in rear. I recently installed Rancho 9000 shocks, setting #5 and this really helped the bounce. Side to side movement is combination worn steering linkage or track bar. I don't think the tires are junk? Just made the other parts of the truck more noticeable because of the harder compound and ply of the new tire vs the old.<br>Steve

 

the old tires were the original 2 ply, 35 psi tires...not sure of the exact size, new ones are about an inch higher...

 

Hey Herber, do you have a lift on there or do those 305' fit stock truck? <br>Heath

 

if ur tire is a &quot;P&quot; rates tire it is designed for a pasenger car. the side wall will not be as stiff as an LT or tire load range &quot;D&quot; also if it a P rated tire u are probably over inflated at 65 PSI. try varying the pressures till u find something that works

 

Heath...I do have a 2&quot; leveling kit on the front, however, 305/75/16's will fit on stock truck and rims. 305's are same profile height as 285's except wider.<br>Steve

 

The stock Michelins that came on my truck (265/75/16) they were 10 ply tires. Rode like a tank even with 40psi in them. Got a set of 8 ply, 305/70/16 tires. Thing rode like a Caddy (so to speak ). Then I got a new set of shocks. Thing rides even more like a Caddy. You can barely feel the bumps.

 

<br>they are &quot;lt&quot; rated and range load &quot;D&quot;...i just changed the pressures but after all these responses i feel better about the tires ride quality....i'm thinking of doing the new shocks mentioned earlier, probably need 'em anyway...Anybody know how much they cost around?

 

On a D range tire (which is too light for the front of the truck) you better check the max pressure on the sidewall. You may be exceeding the max pressure.

 

<br><br>the pressure on the sidewall is rated at 65 PSI...i got the front at 50 and the rear at 60 ( towing to the carlisle mopar show this weekend )

 

Check te shocks, and the tires might be out of round. Could be a combination of the two.
