Switched to 19.5's 3500 Dodge SRW

[Jimf1234]

I've been wanting to switch to 19.5's to feel more secure while towing. I chose the Toyo 608z 265 75 19.5". So far they are great.

Hub concentric will be putting most of the weight on the hub center sticking past the drum or disc base. Lug concentric will carry the weight across all the lug nuts. Typically, hub concentric uses flat lug nuts while the the latter uses tapered.

Thanks I am learning a lot here never given much thought into the rims/tires before.
What is the difference with hub or lug concentric?

American Force, Rickson and Vision make 19.5 rims for 8-lug trucks.

How hard is it to find rims for pick up trucks in that size? I thought that size rim were used mainly in MDT trucks.

Exactly.

Just wanted to make sure I understand...you switched the rim size because the 19.5 tires come in higher load ratings that typical LT tires in the 17,18,19,20 size?

Just a heads up I was told the lowest recommend pressure is 70 psi because of the 15 degree taper of the wheel bead.

This is what stopped me earlier when I checked on 19.5 rims and tires. It's got to be a little ruff bobtail with 70 PSI out back.

It is not so bad for me because I have a 3000lb commercial cap on my truck that gets unloaded only when I will be using the camper.

Nice truck and wheels! Vision or Ricksons? Had 19.5 Visions on my previous 2006 Ram CTD. Nice wheels but had front end woes on 3rd generation truck. Balance, Wheel hub assemblies, and lug studs breaking... But liked the increase in weight capacity.

The aluminum wheels Rickson resells are the Vision Heavy Haulers rated at 4500 lbs each. Rickson's heavier steel wheels are rated at 5000 lbs each which are hub concentric but have a long production time between order and delivery. American Force is the third company that offers 19.5" rims - They are forged aluminum but rated at 6500 lbs each. I don't know if they are hub or lug concentric.

I also ran the Vision rims but with slightly smaller LRH 16PR 245's rated over 4800 lbs each. These were just over 33" tall and matched my previous 275/70R18 tire height. My RAW was typically at 7000-8000 lbs, GVW at 11,500-12,500 lbs and GCW at 11,500-19,500 lbs. The variation depended on whether I just had the camper or both camper and trailer attached and what I was carrying at the time in the trailer.

S Davis thanks I will pump them up.

Grit Thanks for the concern and I will keep and eye on the front end although these new trucks are so much heavier because of the bigger and beefier suspension parts. I had a 2006 mega cab and pulled the same camper and there is no comparison in how these trucks are built.

No problem, I just upgraded mine last year.
