Re: good tire size?

I run 32 Goodyear MTRs on my TJ with 4 angry squrriels under the hood. I've done minor engine mods I get between 180 and 200 miles to a tank I believe it is 19 gallons and max speed is 70mph maybe 73mph going down hill with a big tail wind.

Re: good tire size?

Holy Cow! Assuming that at the most you get 200 miles per tank (19 gallon) you're getting only 10.5 MPG. That's half of what I get right now! [img]images/graemlins/shocked.gif[/img]

To the creator of this thread, I have 30" tires on 15x? wheels. It's a great fit and I still have plenty of power and good gas mileage.

Re: good tire size?

OK
30x9.5x15 are basicly the same size as the 235 75 15.
I have the 235 75 15 on mine, I have 15x8 rims

GO WITH AT LEAST A 31 INCH TIRE
Depending on manufacturer, a 31 inch tire will actually be more or less a 30 inch and 32 a 31 etc... Pro Comp is really bad with this!!! get out a tape measure. With a 2" body lift (cheap, you mentioned a limit in the green) you can fit 32 tires. Remeber though you get no additional flex.

My advise (for waht it is worth)
Set up an account strictly for "Jeep Stuff" stop eating out at lunch, set aside a percent of paycheck, do side work, limit the beer consumption(yeah it can come to that) DO WHAT IT TAKES TO SAVE UP THE MONEY. Then RESEARCH lifts, tires, etc.... ant then you can make the pruchase (this is my meathod and i have $400 saved up in approx 3 months) and dont look back. there is always more you can do, if you are a good wheeler with a bone stock jeep, you should be an excellent wheeler with a modified jeep!!!!!

Have fun
Phil

Re: good tire size?

the TJ has a 15? gallon tank
I get approx 17.5 MPG and I have the 235 75 r 15 tires (30x9.5x15)

PS dont believe me about those two being the same size? Get out a tape measure!!!!

Re: good tire size?

Yes ...err sorta ...they ARE the same HEIGHT within about 0.2" of each other ........but the 30x9.50 has a heavier sidewall and a wider section width..........it weighs much more than a 235/75r15 ....and that's why I recommend it for a 4 banger. It has all the height ....and less mass.

So ..yes ...you're somewhat correct [img]images/graemlins/grin.gif[/img]

Oh ...and I believe the the 4 banger in the 97 and 98 ..and maybe 99 had a 15 gallon for the 4 banger ...(saw it on a sticker when picking up wife's Sahara) ...the 4.0 had the 19.
