What do you guys think about a 275/35/19 on the rear of a 12isf thanks

UCrazyKid

We think 285/30/19 is better...

And why is that and also do you have any pics.

Because 285/30/19 is closer to the original diameter. 285/30/19 is .23 inches shorter than stock while 275/35/19 is .58 taller than stock. I'm currently running 275/30/19 on mine but I'll most likely go with 275/35/19 next time even if it's further from stock.

I went with a 275/35/19R and 255/35/19F because of the poor road conditions where I live. It's a DD that I used to commute from Westchester County to New York City 5 days a week so I needed something with a little bit taller sidewall since I kept getting bubbles on my lower profile Tires. Here are some pics

Yeah thanks guys i also wanted to keep something close to stock ride height so i think the 275/35/19's should fit the bill just right with a little more width Thanks again sweet ride weapon F it's funny my Lexus is the same color lol...ppl just love that color blue....me to.

I'm running 275/35/19 rear 245/40/19 front on 2012 rims. The 0.58 figured quoted by JAT0223 below is the increase in diameter which means it fills the wheel well a very slightly better than stock. The actual ride height only increases 7mm (less than a quarter inch). I chose 245/40 for the front because it is the closest diameter to 275/35 rear. The car will sit level. If you put 255/35 on the front the front it will be 7mm lower than the rear. This would give the car a very slight raked look.

7mm doesn't seem like much do you have a pic of your car

You are correct your 245/40/19F will be closer in diameter to the 275/35/R19 theres .5 % difference between the two but your front tire at 245/40 will be taller just by bit then your rear tire. I've included a couple of different calculators showing the different sizes as well as an overlay of the tire sizes. For steering Dynamics I'd rather have a slightly smaller front tire with slightly taller rear tire, than taller front tire with shorter rear tire.

Thanks again but I definitely would prefer it to be even all the way around or slight rake to the front going to put the 275/35/19 on the rear for right now then worry about what size to put on the front when they start to wear out....Thanks again everyone for your help

I hear you brother good luck with your choice. Just one more thing lol another area that people fail to discuss often is width difference between front and rear tires. If their is big enough difference in width between front and rear tires then the car will be more likely to understeer than oversteer - less grip at the front than the back etc. 255/275 puts you close to square setup their both 10inch tires which puts you into more off oversteer situation. Turn in has improved steer feel etc. I perfer 255/275 setup over my previous 245/285 setup. And your right love my USB F get compliments on the color all the time.

Thanks again bro....yeah my heart is with foxbody mustang lol....and i tell my friends this is a mustang it just has four doors now if i could only make it as fast as the new ones without breaking the bank....lol.

You have several option
1. cheapest fastest way is running Nitros Oxide brother. The ISF luv Nitros, the factory why learns quickly 100 shot no problem. The are entire threads just for Nitros.

2. FULL BOLT ON, headers, exhaust and intake. You can also gut primary cats on oem headers. Draw back its expessive, parts bettween 3k and 4k plus lnstall but you get the biggest bang for your buck.This will give you the most gains

badboylex

Weapon F you act like you have been in a battle with a new stang out there on the road somewhere lol...i would love to beat my buddy 13 mustang boss he makes 447 at the crank.i would love to do all bolt on and a tune and i would hope it's enough to go around him.
