In your opinion, can anything wider than a 275 on the rear, with a completely stock setup, be accomplished?

Anybody ever try 275's all around when all stock?

CTS-V Lee claimed to have had 275's all around but I've never heard of anyone else doing it nor seen any pics.

What is the offset on your HREs? I have HREs also I have 9.5 and want to go to 10.0 on the inner barrel...

I would love 295's out back, but that is probably pushin it. 305's are 12 inches wide, so 2 inches wider than your rims. 275's are 10.8 inches wide, so 2.3 inches wider than my stock wheels ... pretty close to the way yours look. I don't think I'd want the tire bulging out any more than that (and I'm not sure it'd be safe either).

TheLAW - Read above, but also... you might want to reconsider 275's all around. I had 275's on the front and 295's on the rear of my Mustang and those 275's on the front would "track" HARD (IE when you're on a road that's got those dips where people's wheels usually are, it'll yank you all over the damn place). It also KILLS your turning radius, and costs more ... at little to no benefit. IMO Put the big meats out back and leave the 245's up front.

Yeah I ran a 275 rear on a Mustang with 8.5 inch wheel.....goin with a 275/35 on the rear of the V. I saw a Stang with a 305 on a 8.5 wheel...ALWAYS had a leaky bead....I'd be scared it would roll the tire off on a hard corner if you were able to ever get it to seat.

Tires look great Bob! Bob

Those 305's look sick...Yeah no issues with 275's on a 18" stock rim. These are Goodyear Eagle GSD3's than run wide...more like 285's.

I have 255/40/18's on front & there is like.... Less than 1/8" clearance inside at the upper control arm. Can't see how your could get much bigger on there.
But Hey! Didn't think there was anyway I'd get 305's on the rear either, So I guess you never know.

skydiver

You know...... I'm not sure what the offset is after all the widening, stripping, polishing & then rewidening.
Have to pull them off & call the numbers in to hre & ask them what we ended up with on the offset

skydiver

Thanks Bob,
Hope everthing is going well for you.

Looks good! Any issues with the rear end feeling loose because of the tire/rim width difference?

Holy **** that looks badass! How's the grip with them? Any drivability differences that you can tell of? I've said it a hundred times before but I don't mind sayin it again! Bob your V is what got me to want a V in the first place! I dream of having your setup!

And when I do dream of it... it usually turns in to me grabin your car keys at a meet and runnin like hell to your beast with keys in one hand and my passport in the other! Haha jk

skydiver

Haven't noticed any real difference yet... But then I really haven't done anything yet to be able to tell.
Gotta be careful testing tires on the street, Since I've found no tire really hooks on the street and it sometimes hard to tell which one spins the least.
I don't know how many times in just moderate driving I get to thinking the clutch seems to be slipping, When I pay more attention,...It's not the clutch, And it tells in the tire wear. I know I've been gradually dropping the tire pressure on the R888's... trying to get a little better hook just in normal driving.
The R888's are probably not gonna be the tires of my future..... Still gonna have to run a drag radial I think. But at least I know I can use a 305 now.

...hmmm

i have a set of used 305/30/19 PS2's in the garage. i was gonna use 'em as a end tables but perhaps i'll have to mount 'em up on the 505a's i just picked up.

only need the offset arms. also, i hope it doesn't look ridiculous seeing as i'm not lowered yet.

As much power as you are funneling thru those meats I'm sure the only time you would have traction issues would be starting a run at some redicules speed like 150-160mph... I've always assumed that driving around with that much hp and especially tq is like driving around on ice at all times and can never really put down the full potential of your car because of it.... not a bad problem to have if I say so... and I really want to see you take this beauty out to a standing mile event just to see you smash the V record.. I beleave the Texas mile record for a V is 180mph? I'm sure some other fellow Texas guys could chime in on that but I think you really should pull in some records with her...

Thanks, things could always be better... I hope things are going well for you too, hopefully business has picked up for you this year. My brother's Formula is featured in the new GM High-Tech Oct magazine that came out this week, you'll have to check it out. Bob

X2!!! We need HD vids of Bob bouncing the tach off the rev limiter a few times! Or some 1/4 mile passes... didn't he run a high 11 @ 140+ last time? I'm on my phone and don't plan on sifting thru pages to find my answer... lolz

Will 275 or 285 fit with ground forces Coilovers on the lowest setting?
