Tire size differences for hauling

[Beast2B]

my bad, it is a 6-lug hub on torflex type axle. the problem has been finding a tire that stays under 30" with 3000lb capacity. the 225-75-15 is ~29. 5 according to several mfg specs. so far 215-85-16 or a 215-75-17. 5 are closest. good thing this came up or i may never have stopped looking for 5-lug wheels!

problem number two is that it is a company truck and it may take FOREVER for the motor vehicle folks to authorize a change. only took 2 trannies and 3 torque converters on the last F350 Power-joke to get them to come around...

215 85 16 - the Michelin XPS Ribs come in that size as do just about every LT tire that comes in a 235 85 16.

BEAST2B >>>>>> For heavy haulin' the 15" tires are not at their best. For 6 lug six hole 16" see etrailerparts.com for trailer wheels. Great bunch to deal with... ..... JIM

i want to know for those that changed to a G from a E tire. Did you change the rims as the E rims are not rated for the pressure of the G tires?

 

[PatrickCampbell]

Another question: Where do you see it on these wheels the rated pressure. I can't find it anywhere on any wheel I've ever had.

 

[champspa]

I don't want to steal the thread but at SouthwestWheel.com every wheel has a rating and the question still is does the dodge oem wheel rate for a G load ?

I have never been able to figure this out. I just got a brand newset of wheels and there is absolutely nothing stamped on them.



I have some wheels that have the size stamped on them along with "JJ". Some people have said that "JJ" means 80 psi but I do not think this is correct.



I quite sure that "JJ" has something to do with the tire profile or bead profile or something like that but not the load rating.

I do not see anything about wheel ratings there but it's a long page. Did I miss it?

Example:... You'll notice it reads "6J x 14 H2 ET45". The "6J x 14" part of that is the size of the wheel rim - in this case it has a depth of 6 inches and a diameter of 14 inches (see the section directly below here on wheel sizes for a more in-depth explanation). The "J" symbolises the shape of the tyre bead profile. (More on that later)



Only has to do with the rim shape/conture...
