Front wheel fitment question

hi guys. quick question can I run a 19x10 et42 in the front? with say a 275/35 or a 265/35? is brake caliper clearance the main issue here?

I think it will fit, but I'm not 100% sure so wait for second opinions. I can say that I run 19x9.5" 275/35/19 in my front. My wheel has 33mm offset with a 6.5" backspacing and there's tons of room still around the caliper. I wouldn't, though, put a 265/35 on a 10" wide wheel, it will be stretched on the corners I think. 275 minimum to avoid warping/stressing the sidewall.

I was only thinking 265 in an effort to make it fit. If i can i'm going to try 285/35's and run square.

I'm trying to fill out my front wheel wells more. The 19x9 et35 with 255/40s look terrible.

You might get some wheel well rubbing with 285's in the front during nose dive conditions, but again, its just my hunch.
 
The biggest clearance issue up front is the strut/spring. I think most 285's clear with no issues.

supposed to be pretty warm this weekend (50s :'() will have to give it a try and put my rear tires on the front and take it for a good ride. the 19x9's look anemic in the wheel wells.
 
I have only driven my car with 275s all around until Monday. I ran 305s on 18x10 wheels and had no problems.

I don't know what the offset was (they were borrowed) but it was the BBS 18x10 that Rehagen sells.

Clearance to the caliper is usually determined by the type/brand of wheel. Also of concern on the backside are the swaybar endlink bolt (which many cut down), fender well liner at steering lock to lock, and the front springs.

That said, I think ET42 for 10" wide rims seems to be the best compromise up front. Vorshlag uses ET43 on their D Force 18x10, and ET42 for their Forgestar F14 18x10, both of which are supposed to clear all four corners, depending on tire selection. Same should be true with 19x10 rims.

What brand are you thinking of running?

I have forgestar CF5s now 19x9 and 19x10s. I want to replace the 19x9s with 19x10s for the fronts. I can test this by taking my existing 19x10s and putting them on the front but it's still like 20 out right now so i'm trying to put that off for warmer weather. just thinking the stock 285s are too wide so 275s?
 
if you search some of the other forums, theres guys that have or are running as much as 315's on the front. You might find some usefull info here ,

and I know ford makes an 18X10 that works for the front or back, so 10 inch wide rims do fit, just need the right offsets.

Another source would be Sean Thompson at Steeda, very good with what fits and what won't.

Also add to this that the front swaybar endlink can be a clearance issue. Note that the upper mounting bolt has 1" of non-threaded hex on it that can come VERY close to the tire / sidewall. Feel free to take a cutoff wheel to it to make more clearance.

Note: I had to do this with 18x10s (D-Force) with 305/650/18 as corner loading tended to produce smoke and rubber buggers from the inner sidewall :)

Jeff,
Do you have a pic of your car with those rims? I ordered around Xmas time and I can't wait to see how they will look on the Boss!

not very good but....also think it will look way better when the wheels match in concave(ness).

Now you've got me curious...next chance I get, I'll try my 19x10 F14s with PSS 295/30s up front.

I might just run that way and get a custom 19x10 for the rear that will tuck in a bit better, like 3-4mm more.

i run a square 285/35/19 on my stock 19x9 brembo pkg wheels. they have a +42 offset. the only rubbing i get is a slight amount on the brake duct hose at full lock. i am working on a new set of 18x10 +45 track wheels with 285's. they are perfect all around, but i am looking into a +35 for the front (rear doesn't work). with additional camber, the +35 will tuck in perfectly and i will gain 20mm of track width on the axle that needs it the most!

I might be able to take my snows off the front saturday and give it a shot weather is looking ok. 50s but might rain. will have to see. I will probably stick with a little smaller tire in the front 275/35?? I really lucked out with my c63 and got amazing fitment with a set of kleemann wheels, I want that again.

I am also looking into a 19 x 10 fitment for the front. Has anyone heard/seen of anyone with a Boss going to a 19 x 10 and a 19 x 11 staggered set-up? With the Michelin pss they have a 275 35 19 size (26.6" height) and a 295 35 19 size (27.1" height) or going up even farther they have the 295 for the front and a 325 30 19 for the rear (26.7" height). I am not sure what effect tire height differences have on stability control/ABS as there is .5" and .4" diffrence bewteen the 2 set-ups. Grant 302, I would be interested in how you like the 295 30 19 Michelin pss on the 19 x 10 F14's. Are they a bit too big for a 10" wide wheel or are they a good match?

Visually and aesthetically, I think the 295s look good on the 10" wide rims. Sidewalls look close vertical. I'd say less bluge than the stock 285 on the rear 9.5". 30 series are a little short looking for the street and the 35s would definitely look better.

But for the track, I think both these and the 265s on 9" have a LOT of sidewall movement, even with 40+ hot in the front. But it might be that this tire needs 45+ on the track for such a small tire turning a heavy car.

Cool, thanks! I ordered the silver in 18x9.5 and 18x11's. I havn't decided which nitto's yet the nt01's come in 275/35 and 315/30. The nt555rii's come in 285/35 and 305/35.
