Tire Rubbing issues & speedometer calibration…

![Default](https://dodgeforum.com/forum/images/icons/icon1.gif)
Helllo all, new guy to the forum here. Didn't know where to go for answers and I found this forum. I did search for tire rubbing and came up empty
.
I have a stock 2008 Ram 2500, 5.7 Hemi and I am wanting to put bigger tires on for the sake of more weight bearing capacity. I believe the stock rims are rated for 3,450 and Nitto Terra Grappler tires, size 285/70/17 E are rated for 3,750 per tire versus the standard 3,195/tire for 265/70/17. The truck came stock with 245/70/17. I’m wanting to compensate for the weight of a heavy camper. I’m planning on adding a leaf, sway bar, and possibly helper springs (Super Springs, maybe Hellwigs).
Will the 285’s rub at all? If I go with 285s (or 265s for that matter) will I need to have my speedometer recalibrated?
Also, I haven’t done all the math on what my GAWR is/will be. Right now I know I won't be overweight with my current camper, but I haven’t had it on yet (new truck, camper is still snowed in), and I do plan on buying a bigger/heavier camper.
Any ideas whether these tires will rub and if I'll have to recalibrate the speedometer?
Thanks,
Tim

i think any tire size change from factory would require a speedo calibration.
get yourself a superchips!
i run 285/70 r17's with no problem all i have done is a t-bar crank im wanting bigger tires think im gunna go with 33x12.50's which is said not to rub with a level.
so on size you should be good, as for the weight, i failed math class so cant help there.

Do yourself a favor and get Air Bags instead of an add-a-leaf, better ride, better capacity, better all around...

BTW, anyone got a link so I can read more about superchips?

I really don't care about being off on the speedo, I have a gps I toy around with when I drive. Is there another reason to re-cal the speedo? Doesn't the tranny shift based on truck speed? Or is it rpm? If oversize tires aren't going to screw me up somewhere else I don't really see a need to recalibrate.

I've had both and I'll never do helper springs again after having bags.
For a 2500 series truck, there are bags with a 5000 lb. capacity, that's 5000#s of combined bed/tongue weight, not towing capacity. Yet, aired down, it's like they are not even there. I have not seen ANY springs with that type of capacity....

What's the name of the air bags you're talking about? The only thing I've found locally is Firestone Ride Rite air bags. I didn't know you could get bags to compensate for weight too, I thought they just helped with lift. Give me a brand name if you would, and I'll search 'em.
Thanks,
Tim

I have the 2000# Ride Control series. With 10# air, the rear of my truck is no higher than before I put on the bags. For sh*ts and giggles one day, I filled them to 100% capacity and the EMPTY bed only rose 3/4"...
