Default Using new 18" rims on my lowered mustang

Any problems with that?

Mustang Tuning has the deep dish chrome on sale this month.

I want to go with 18 x 9 in the front with 255-40-18

And 18 x 10 in the rear with 275-40-18

Was worried about rubbing?

Thanks

Any suggestions on changing the tire sizes?

You should be fine a lot of others are running the same size.

What about the same wheels and a 305/315 tire in the rear.

someone on here has 315's and they stick out past the fenders. While it looks good with a nice fat back tire I think 295's are as wide as you can go and keep it in the fenders.

I have the 295's in the back, and they line up perfectly with the body line. If I can figure out my wife's digital camera, I'll take a picture along the body line and show you.

I wish you would. I have decided on 18 x 9 deep dish with 255-35-18 Nitto in the front and 18 x 10 deep dish 285-35-18 Nitto in the rear.

I would like to have gone to 40's in the front and rear, but I cannot find a tire maker that has the 40's for both the front and the rear.

I was also concerned with my steeda springs causing a problem. JJ Stang, You said your rears are 295's, did you lower your car?

Those tire will look very lowrider in my opinion.
The rears (295/35/18)will be 1.05 inches shorter than stock and the fronts (255/35/18_will be 2.15 inches shorter than stock.
That will affect speedometer, final drive gear ratio and top speed. It will also look out of proportion with the front tire having such a short profile.
Did you research the tire height before choosing this size tire?

Ah! Research. Could you define that for me kopfjager, `cause I don't want to look it up. [sm=icon_rofl.gif]

Sorry, I couldn't help myself...

Ok, I could, but I'm having too much fun with the smileys today.

Seriously though, the Michelin Pilot Sport PS2's come in 255/40 and 275/40 sizes. That's what you had in mind, no. But the 255/40s are going to be 1 1/4" shorter than stock 235/50s...so you have a significant speedo error (5%), and possibly (I hear) problems with your antilock brakes acting up. Scratch that--the difference between the stock and 255/40s might cause a problem, but the difference between 255/40s and 275/40s is about 1/2" in height, so that may not be enough to freak out the antilock processor.

Actually, you guys seem to be comparing apples to oranges. If the stockers are 235/55 17's as they were on mine. You can go to a 255/45 18 as I did and all your speedo etc. will be the same as the actual circumference of the tire will stay the same. Just go to tirerack.com and look at revolutions per mile for your tire sizes in question and make sure they are similar or you will have those issues. And of course a programmer will solve the speedo issue if you decide on a different circumference. Dunno about the antilocks though.

As far as the rubbing goes, I haven't had a rub yet, but then again, 255's are a mile away from 315's, so you're on your own there.

I have 255/45/18 and 285/40/18 both very close to overall stock height.

Whose Apples, whose Oranges!? Whose on First? I wanna be an Orange. Man has it been a long day at work! [&o]

Good point Scooter. But the stock 18" upgrade wheels are 235/50s.

Anywho, there's a really slick tire/wheel calculator available from Rick Tolan:
http://gs.tolan-hoechst.com/tirecalc.htm

Uh-oh, research tools, now we're getting dangerous. I'm also fond of stuff that has proven it works--ex: Roush runs 18x10" rims on all four corners with 275/40s on their new StageIIs (which are lowered). Rumor has it that they use +45mm offset (that rumor has been rather unscientifically confirmed by me, but at the moment I think it is correct). Bottom line is that I don't think you should worry too much traffic, what you're interested in can be done. Pip-pip, chin-up, cheerio good man!

Also, I've matched Tolan's calculator results to other data available, so I'm inclined to trust the conversions it produces.
Best,
-j

Okay, so I'll want a 295 series tire then. I want to hit up as much as possible, rubber wise, without affecting the appearance of my car.

So, what size tire do you reccomend? I've got a 1"f/1.5"r drop (18x9f/18x10r wheels.)

I want to keep the OD of my tires (relatively) the same as the O/D tires.

Default RE: Using new 18" rims on my lowered mustang

I have a lowered GT with 265 35 r18's and the ride is very firm. 35 series tires make for a rough ride. Also, your risk of damaging the rim increases when driving over pot-holes and such. There is still a lot of room before rubbing. You may also want to consider the offset of the rims. The lower the number offset the farther the rim sticks out. I have 45MM offset same as stock. My advise is to not go lower then a 40 series tire.

Also, a neat trick is to get all the same size tires all around and get a high quality spacer (1" or 1.5") to make the back look like they are wider. This will be better on the wallet and make tire rotation easier. I think I will go this route with my next set of tires.

+1 on the "don't go lower than +40mm offset"

Correction: the OEM 18x8.5" bullit wheels have +50mm offset. 17x8"s have +45mm offset.

On a Side Note: Mr.Mustang, your avatar scares the bejesus! out of me every time I see it.

Best,
