i'm in the planning process of changing the wheel and tire combo of a '98 Ram 1/2 ton 4x4. the combo i really like the look of is the 20" wheel with some nice off road tires (none of that lo-pro stuff). what would it take to put that set up on my truck? will i need to lift the truck? if so, how many inches? this will be my first lifted truck, so any pitfalls, do/do nots etc etc would be greatly appreciated.

I'll give you some tire size's and specs, maybe that will get you headed in the right direction,,

The Big Boy is a 38/15.50R20 , Overall Dia.- 37.8 inches, width - 15.4
37/13.50R20, OD - 36.8inches, width - 13.5inches

325/60R20, OD - 35.2, width - 13.2

hope this helps,, did I mention that I sell these on my e-bay store?? mitchwheels35

thanx for the response MT.

10" lift 20"wheels and a 38 to 40" tire for some pics goto www.wholsalesuspensionoutlet.com

i'll check the link you posted in as soon as i type this, but is it possible to not go that high? that seems like a huge lift. if i go with 35's, will a 4-6" lift do it?

Smart thinking- over 35" and you'll have inadequate braking as well as diff ratio issues. You'll have some problems in those areas at 35 anyway. Don't attempt to tow anything with it- it won't stop.

i have a 99 f-250 xtra cab diesel with 305-50/20's nitto grabblers and had a slight rubbing issue when turning lock to lock. was just going to do a leveling kit which would have fixed my problem but for an xtra $800 did the full fabtec 5.5" kit...came with all the hardware NEW front leafs and front and rear shocks

i do use this truck to pull my boat with. from the sounds of it, i'm better off not to lift it and find a wheel/tire combination that will work without the lift. i hadn't thought about the braking issue by putting on larger tires and a lift. is it safe to assume that i would also lose some of the power because of the tire/wheel change?

i had a 96 dodge ram on 35's. they were swamper 35x15.50x15..with the 6 inch skyjacker lift they would rub some under a full turn. 35 with a 20 in wheel will look low profile. If you went to 35's you would need to change the gear ratio as not to lose any power. breaking in my truck wasn't bad...it stopped fine pulling. but it wasn't the same as stock and with a that much wheel and tire you will lose some stopping power. later did some custom lift and ran 38's...didn't pull much more than an airboat at the time, they don't weigh much. Now it is on 44's but thats another story

i noticed a minimal acceleration loss, and no change in breaking with mine
