Moms ZJ needs new tires. What size is to big?

My mom ( 65 years old ) drives a 98 GC and is in need of new tires. The Jeep is not lifted and never will be. Its just daily transportation for her. Back in 08 we picked up a set of the 15x8 black 5 spoke Jeep wheels you see on Ebay all the time and put some Dunlop AT radial Rover 245/70R15 tires on them. Even at a 245 the tire looks a bit small on the rim but she loves the way it looks. Well she is due for new skins but that tire size is no longer being produced. Before I go hit a few local shops what have you guys run and what would you recommend?

Generally a 30x9.50x15 tire is the largest you'll get on a stocker.

Size 30 like said is the biggest you want to go but for her there is no need to go bigger. It's just a DD that never see's off road. Bigger tires = less power, less MPG, more weight, less stability on road, ect.

Thanks for the input. I want to get a meaty tire that does not look goofy on an 8 inch wheel. A lot of sizes are drying up for the 15 inch wheel.

235x75r15 is a decent size.
or the 30x9.5 works too

I have 235/75R15 on my XJ and they look ok on the stock 7 inch wheel but would look stretched over an 8 inch wheel. For an old lady she does really care about how her Jeep looks. Back in 08 when she wanted better looking wheels the guys at Discount Tire sold her some aluminum wheels that were the wrong offset and stuck out way to far. She made them take them off and refund her money. I then helped her get the Ebay wheels and used the bad experience she had with the manager at Discount Tire to get her a good deal on the Dunlop's she has on now.

I'd just run stock size (235/75/15), especially for a stock vehicle that gets driven only on the street.

stock is 225 not 235..

Im using 235/75/16 on my 5.9 thats 30 inchs, i had to trim my bumper slightly so it would stop rubbing when i backed up turning the wheel.. My mom uses 235/75/15 on her 4.0 that is 29 inchs, reason is because my rims are 1 inch bigger hense 30 inch vs 29. stock tires were 28 inchs.

If you want max size you should get 245/75/15 that is a 30.5 inch tire.. altho it might be a TAD too big.. so a 245/70/15 which is 28.5 inchs might be a better choice


I love this tool for finding tire sizes in inches

Just for around town use, P235/75R15. P225/75R15 is the stock size, but it looks a tad too small in my opinion.

XJ90 - I had not looked at the 255/70 options. I might see what the shops here can get in that size.

31x10.50r15 will more than likely rub when at full lock, flex isn't really going to matter since it's not wheeled as you say.

225/75/15 was indeed stock, but 235 was an option, even from the factory.

Here are 30x9.50r15 on mine way back in the day. Mind you, those are the stock 15x7" rims, so an 8" rim will look a tiny bit different.
