any one have experiences with these? im looking for cheap tires for my jeep zj

also anyone have any thoughts about putting p215 70 15s on my rims. the current tires are 235 75 15
and im pretty sure OEM is 225 70 15

i think it would depend on how wide your rims are, plus they will be shorter, so your gearing will differ

is there a way to tell how wide a rim is? i have no clue where to search.
this is a factory rim on a jeep grand cherokee limited
is what it looks like.

On every vehicle sold in the US, there is a sticker - commonly called the placard - that will list the original tire size and the vehicle manufacturer's specified pressure for that size. The placard is usually located on a doorpost or in the glove box, but sometimes it is located in the trunk or on the fuel filler door.

My book does not list a Jeep ZJ, and the listings for Jeep CJ's list quite a lot of different tires sizes as original. What do not want to do is go smaller in load carrying capacity. That increases the risk of a load related tire failure - which sometimes has tragic consequences. So if your placard says the original tire size is a 225/70R15, do not use a 215/70R15.

Not to mention that you'll get better fuel economy with a larger tire.

according to this Sizes To Fit Your Vehicle
the size you currently have and what size you think was stock, could both be stock sizes.
It's probably a 6 or 7 in wide wheel. If it is a 7 in wide, 215 may be pushing the limit for narrow. If it's 6, you shouldn't have a problem. Any easy way to know how wide the rim is, is to measure from wheel lip to wheel lip, just stick a ruler or tape measure through one of the openings, and get something flat to place across the front and back side to get a some what accurate reading

Maybe... Maybe not.

They are 15"x7"

You look stock at 235 although 225 sounds familiar

hmm if its 15x7 i should be okay with 215s because the max width for 215s are 7in. and the sumitomos are well over my GVWR. i think my curb weight is mid to high 5000lbs
and these tires are rated 1600s each, which is at least 6400 total. I might shoot for the kumho 215 75 15 since theyre slightly bigger so i wont get such a big speedo error. I wanna switch to something thinner width wise to improve my gas mileage, and more just because i dont need such wide tires, but this also means i will need to replace my full size spare. my jeep is all time all wheel drive.
