Good Morning,
I recently purchased a 24 ft RV on a C30 chassis . How do I determine how heavy it is ? And what load range on the tires should I should purchased ? It Currently has LT225/75R16 Load D . They are dry rotted

Thanks for any ideal and suggestions

Welcome to iRV2.

With the existing tires being dry rotted , driving to a scale is probably not a good idea.
Do you have any additional info to share ; chassis year ? registered GVWR ?
RV manufacturer ? Existing tire brand ? Any decals on the coach stating that the LT225/75R16 Load range D was the original equipment size and rating ?

JMHO; Because older class Cs are most often, at or over, their registered GVWR , new tires with at least a Load Range of " E " would be in order.

BUT , that could change pending more info .

A quick google search turned up half a dozen truck scales within just a few miles of Concord NC

Don't cheap out on tires. They are the number ONE safety item you have going down the road

Should be the oem tag in door/jamb area. or you can run the vin and get close.. BUT most RV manufacturers re classify. my minne is 11400 from ford but winnebago redid plate to be 12400 as the beefed chassis for design..

IMO also LT225/75R16 in the "E" is customary for most older c class..

I have located a label that had been peeled off and stuffed in a drawer. the existing tires are made by Aurora in Korea ,
On the Label is printed
10,500 GVWR

Front 4500/1814
Rear 7200/3266

I assume it would be safe for me to assume 12,000 would be a good inflated number in the future ?

Thanks

Here's some info on your size ( LT 225/75R 16 in load range E ) from the Michelin site , note it doesn't appear they make a load range "D" any more, that rating not shown in the charts .

Max load , single @ 80 PSI 2680 lbs, per tire so 5360 on front axle

Max load , dual @ 80 PSI 2470 lbs per tire , so 9880 on a dual wheel rear axle.

Other tire manufacturers load range E should be VERY close to these numbers , so load range E , is the way to go.

Once you have good tires on the RV , and get your loaded for travel weight , you can probably lower the tire pressure ( according to manufacturers charts ) for a smoother ride.

Most people will recommend Michelins, but Hankook and Nexen have some good ones. People are using them with good results. Leprechaums are coming with Hankook this year in many models.

Many people here will only use top brands like michelin......

I have since 2008 in my 94 e350 Shuttle conversion weighting 10420 empty.. used generic brands from my tire suppliers,, $68- $85 dollar tires all load E..
Over 62K I added onto the rig.. Fronts would last 12-15K rears 20K+.. my Towing various weights messes up frt alignment..

I did eco brant to keep a bit more agressive a/s thread and keep fresh for going in fields and winter..
