Are Swampers Bumpy and Lumpy?

[Hubnut]

I bought some swampers (TSL not radials) for the first time for my truck. On the road this morning after having it parked for a few days, I experienced a bump bump bump coming from one of the tires. It seemed to get a little better with time, but not much. I checked everything when I got home and the truck seems fine. Are these tires just not very round or something?

Welcome to the wonderful world of Interco tires... they'll round out after a couple miles (depending on the temperature)... but yeah that's normal.

that sir is called old school bias ply tire flat spoting.

drive them for a bit each day and basicly no problems.

let them sit a few days or weeks and it takes much longer to warm up and ride nice.

Thank you guys. My military truck tires do the same thing. I figured a civy tire shouldn't do that. I love them off road though!

They're really gonna have flat spots on em when i get my Blazer going

Or as I call it, morning sickness. The first time I experienced morning sickness was after I bought a set of 33" Gumbo Mudders on white spoke rims off a guy at work. I put them on in the middle of the afternoon, and come morning, I was scared sh%tless I screwed up my truck.

When you first start the truck move it a few feet so the bottom of the tire is no longer on the bottom. Let it sit for a few minutes then go on your way.

I used to do this with my bias plies. 90% of the time I had FAR less bumpiness after doing this.

Try driving a set of 37" Iroks at -40c...They feel like you're driving square tires...lol

 

[Hubnut]

Cool. I get the idea. I thought the truck was broke.

Yeah... winter runs with bias tires is always fun in the morning. Then add on all the snow/ice that has molded itself to the rim... can make it feel like the truck is bouncing off the road!

Uh, do bias ply tires have "steel belted" markings on them?
