Gents I'm pulling a 14 Cyclone 4018 TH , empty about 15k, GVWR is 18k. I am about to trade out the blow max China bombs and am fairly well convinced that the S637 are the exception to the no-Chinese rule. Question: the TH bounces down the road like a superball now, have any of you suffered a worse, bouncier ride after trading to the S637s from an E rated tire? PS I will be trading 235/80R16 blow ax 80 PSI for 235/85R16 110 PSI 3750# skins. Comments very much appreciated.

Mine rides very well with the Sailuns inflated to 100 psi. I run them at that because it takes a long time for my little compressor to get them up to 110 psi. And I'm only carrying about 12,000 lbs. on my 3 axles. A bouncy ride sounds like something is way out of adjustment, I've never seen that.

I went from LRE china bombs to G614's (same thing as the Sailun's but made in America). No difference in ride of the trailer whatsoever.

Ive seen some number other than mine that bounce down the road. I have learned to secure the bikes down really well and to stop and check the load periodically. The garage on these THs bounce A LOT.

They are a darn nice tire for the money, but BIG! Much wider than your average 235 tires and the bead thickness is massive. Had a hard time mounting them on aluminum wheels with a narrow drop center.

Mine are on a triple axle toyhauler.

for the Cyclone owners: after measuring my tire to tire clearances I was worried about the ~1" larger diameter of the Sailuns, but decided to take the plunge. The result is that clearance between the 2nd and 3rd tires is tight, but no problems so far. I can't answer my own question posed at the top of this thread because I haven't put any miles on the sailuns yet. Will keep Yall informed.

I thought most people running the sailuns were putting them on a 2 axle. I thought the people with a 3 axles were going with a different brand/size?

I had to buy a new rim for my spare only as it was steel but my running wheels where high pressure rated aluminum. I purchased mine online and had them mounted/balanced locally for $16 ea.

The s637 weigh 61lbs vs 31lbs for the blowmax. These tires are very sturdy!
They are larger and I modified my wheel well to avoid any problems over larger bumps.

The above statement says it all when it comes to the quality of the tire.
I still have my OEM rims

My wheels were fine for the uprated Saluns.

Did any of you guys have to change wheels to accommodate the higher tire pressure?
