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. [image]

They don't look like 19.5s to me, looks more like a 17"-18" wheels unless pics are before you put them on. Not saying there not but sure doesn't look like the 19.5 setups I've seen in the past.

Must just be a optical dillusion.

My truck came with 285 20's. These are 265's but because of the wheel offset they stick out just a little bit but are the same height. These tires are BEASTS. They are rated at 5500lbs each at 110 psi.

I have been thinking of upgrading to a Toy Hauler but will be over my tire ratings. My truck weighs 10k pounds with me in it ready to tow.
Here is my slip with my current camper and it's not a heavy unit.

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.

I am confused is the new toy hauler being considered over old tire ratings or your new ones?

Cummins12V98 I'm guessing that his aftermarket bumper added more weight to the front. Just guessing.

Posted By: Jimf1234 on 04/01/17 09:14am

cummins Yeah my bumper and winch weigh 400lbs. Most of the toy haulers I have looked at have a pin weight around 4000lbs and since I have a srw I wanted more capable tires. These are rated at 5500lbs vs 6170 for drw. How much transfers to the front axle of your truck when hitched up? I got less than 100lbs with my old 2500 mega cab.

Me again Wheels

Alex They are stiff but at 65psi they are comparable to my stock tires at 80psi.

Blofgren The stock Firestone 285 60 20's are 33.4" tall with a max load of 3640@80psi
The toys 608z are 265 70 19.5 are 34.1" with a max load of 5500@110psi

That's a lot of weight on the steers for a pickup!

Thanks! That makes sense.

I add around 150# to front axle with 5er attached.

Posted By: Jimf1234 on 04/01/17 10:36pm

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.

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.

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.

Posted By: rowekmr on 04/03/17 04:40pm

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?

Exactly.

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.

Posted By: Bedlam on 04/04/17 06:44am

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

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?

Posted By: Bedlam on 04/04/17 09:35pm

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.
