Put in monroe reflexes, which did not make much difference as I suspected as only one of the old shocks was noticeably bad. Anyways the truck still feels like its hitting three bumps instead of one and gets really shakey up and down like at certain speeds on poured concrete highways. It only goes away when I get it up to 80 mph and it rides just fine.

 

What's your tire size and pressure?

 

35,36,38,38. Fd,fp,r,r

245/75/16 all around.

 

Might drop the pressure a bit. Narrower tires don't need as high a pressure on these trucks as the wider ones do.

I have to run 45/40 in my 285s because if they're at stock PSI they ride like crap. lol

 

run less in the rear?

 

Yeah, less weight. Unless you haul on a weekly basis, there is no reason to have the rear at a higher pressure as there is no weight back there.

 

makes sense, I haven't checked the pressure ever.

 

I have the stock size 245's on my truck, too. Last week, I had to put new ones on. Granted that my old ones were Dunlop and the new ones are Goodrich (both 10 ply), I think the age of the tire makes a difference in telegraphing the impact of bumps into the chassis. I think the compound hardens a lot over the years. Just my $.02. Anyway, it seems like the ride is better now in that the "wham" I used to get on a pothole edge is a lot less.

Between hardening as they age and whatever amount of compliance you get in having more tread depth in new tires, I'm a lot more comfortable now compared to last month.

How old are the tires?

--VARam1500...

 

not sure but probably old. they are getting down there in tread. but not cracked to much

 

How long did you let it go before changing the shocks?

Worn shocks allow wheel hop... wheel hop will cause uneven tyre wear...
You change the shocks, but the unevenly worn tyre is now the issue, and will wear the new shocks out quicker... 60-65mph is where the wheel hop shows up (for me), but I'm sure this is likely tyre size dependent... by 70mph it's gone.

Bottom line, change shock at the first sign of going bad, before you spoil tyres with good miles left on them.
