I'm looking at putting larger tires on my Ram. I just bought it a couple months ago and I am still learning what the old owner did to it (came from a dealer with only a partial history). Any way I was underneith it today when I realized It already had a 3" suspension lift. Not sure on brand yet, I just noticed the spacers.

Now for the questions. I know absolutly nothing about putting different sized tires on a truck. I currently have undersized tires on it. I would like to go to stock size at the minimum and maybe larger. So what size do you all think i should go with. I would prefer to stay with the stock rims if at all possible.

Also do I need to worry about upgradeing brakes or anything else to go larger? And what effects will bigger tires have on my performance?

 

What is undersized? Mine came with 225/75/R16s from the factory. With a 3" lift you can fit 35s at max but 33s or 285/75/R16s are more practical. Do a search on this topic, it gets covered every week.

Large tires like 35's will significatly reduce power and fuel economy without regearing. Also any larger tire will more than likely reduce fuel economy due to increased inertia.

When you say spacers do you mean on top of the coils or blocks in the rear? The 4x4s came stock with 3" rear blocks.

 

Stock was 265/75/16. I can double check the rear. There are blocks on the coils. I also measured the rim to fender distance which is the same as my buddys lifted Ram.

I bought a full sized pickup, I'm not too worried about fuel economy.

 

There should be a sticker on the driver's side door that states the recommended tire size. Stock tire look small on a Dodge.

 

i have 265's and it doesnt look small...

 

larger tires change your effective gear ratio and make your truck more of a pig.
285/75-16 are about the largest you can put on stock suspension, so if you've got some lift you can take it up from there.
be aware that the 3 inch blocks in the rear are stock.
the stock front end doesn't have any blocks.
stock brakes aren't very good to begin with, so they'll get worse too.
not a lot of options on brakes except slotted or drilled rotors.
see if there's a upgrade to a dual piston caliper, those came on the 00/01 and are pretty good improvements.


my opinion is that 35's are about as big as the truck can stand and still drive decent. they require some lift.

 

I beg to differ, 35's are a beast to get going on stock gears. 33's are better, butt prolly the best I have found for over sized tires were 32's. Fill up the wheel well nicely and are not to heavy.

When I went from 33's on a 15inch rim to 35's on a 15inch rim it took a lot more skinny pedal for regular go, and all the skinny pedal for super fun go.

 

I would say stick with 33's or a 285/75/16 and you will be best off, they will look good even with the 3" lift if the truck has it, just measure the front coil spacer and the back block, anything over 3" in the back is not stock

Oh yea we like pics too
