definitive tire, wheel, and offset thread

[G2]

Wait Gary, so I knew you were somehow in the auto biz but, are you a dealer for certain wheels? If so PM me your info.

Yes, for the one's mentioned so far. Working on other brands also. What are you looking for?

PM'd.

OE tires are 255/40's, O_E.

(Even the C5-A6 4.2 uses 255's)

Thanks, was thinking tread width not section width, and tires from a different vehicle. I guess we can tell who got an early start on St. Patrick's Day!

Here's my RS6 with 20" x 9" Sportec Mono 10 (forged) wheels. ET35
I'm running 275/30/20 tires, and due to the more squared shoulder of this Toyo T1S, I've had to run a 5mm spacer to bring the offset to the proper ET30. It was rubbing on the nub of the control arm.

I'm going to play around with some spacers that I ordered and see if I can't find that fine line between getting them out to the edge, but not rubbing or having to roll the fenders.

Purrrrrdy! How's the ride on 30 series / 20" rims? I've been debating looking at 255/35/19 setup to get a bit more clearance around the caliper, but anything that lowers the total weight is crazy expensive (more than I'm spending on a commuter vehicle for the wife), while lighter weight 20's are coming in cheaper...

I don't use facebook, what brands do you sell?

The tires that I bought with the wheels were 245/30/20. The ride was quite rough. They were Vredestein Ultrac Sessanta. they had a very low sidewall, and quite a rounded shoulder. Again, not a good ride, but I was going to tough it out. Fortunately, I hit a pothole and was forced to replace the tires. At 275/30, there's quite a bit more sidewall, and as such, the ride is great. The squared shoulder of the T1S should offer significantly more rim protection as well.

The list is long and wide....most anything-- including anything from TireRack. Can dropship from them on bigger orders to also save shipping costs. Some high end wheel companies require a Buy In to setup a wholesale account. I can do this for people who want a specific wheel. Either way will save some on overall costs. Maybe even avoiding sales tax.

Generally I am focusing on closeout items, or high value/quality wheels and tires. Right now I have a set of Bremmer Kraft 19x10 ET35 10 spoke wheels. And blowout prices on matching tires. Admittedly this fitment is extreme and will take some coaxing. Think "Stanced".

Been working with Forgestar wheels, on behalf of a RS6 owner who wanted 18's. We found a classic 18x9 (or 8.5), 5 spoke flow-form forged in the USA made wheel will fit the RS6. There's custom offsets, colors, treatments (polishing, paint), w/o breaking the bank. Well under $500 per. Right about 21-21.5lbs depending on ET, and plenty strong. Almost bet the ride quality improves with such a weight loss. Downside is lead time is typically 4-6 weeks.

Prices haven't changed since 2009, which is impressive. See how long that holds out.

I might be able swing some sort of group buy. Or ply some friendly pressure to reduce production time on a handful of RS6 specific wheel sets.

Just got my OZ Superturismo LMs in matte grey, they are 19x9.5 with a 30mm offset and I mounted 275/30/19 Sumitomo HTRZIII's. They fit perfect w/out a spacer and drives 10x better than my old 20" OZ Ultraleggara's

18x8.5 offset 32 will fit right? Those 2 mm's aren't a dealbreaker right?

1/8th inch closer to the strut, not a dealbreaker so long as you're not running wider tires / lowered suspension. What kinda goodies are you looking at?

BBC RC's that are painted black. Going for weight savings...

Can anyone help me with a quick calculation?

I have a set of 18x8.5" +45 front and 18x9.5" +45 rear Prodrive GC-012L forged wheels left from my Subaru. Stock wheels are apparently 18x8.5 +30?

The Prodrives are 5x100 so I'd need adapter spacers and I'm not sure how they'd look with 255-width tires on staggered wheels, but if I were to make them work, what size adapter/spacer would make them sit pretty flush? The fronts are about 15mm higher in offset than stock and the rears should be 10.4mm lower if my math is correct. I paid a good amount for these special-order wheels and they're lightweight and look incredible, so I'd love to not have to sell them at a loss and instead re-purpose them on the Audi (if possible).

On ECS Tuning's website I see I can opt for 20, 25, or 30mm adapters. Should I perhaps go 30mm up front and 20mm in the rear, or...?

Front: Your new setup would be 15mm closer to the strut
Rear: Your new setup would be 27.7mm closer to the strut

Fronts you'll want 20mm if you can't find 15mm, but you'll need to roll your fender lip just a hair if you're lowered.
Rears, go for 30mm for the stock look plus a tenth of an inch

Stagger your tire setup! 255/40/18 on the front is within .4% rolling diameter (well under the margin of error) of 295/35/18 on the rear, and the tires will have a better approach angle on those 9.5 wheels, good squared shoulders almost equivalent to the 255's in the front.

Maannn those prodrives with some concave on the RS.... droolll

[Dmb408]

would you guys ever run wobble bolts for 5x114.3 wheel to our 5x112 pattern?

I'd rather run an adapter than wobble bolts. You're putting a lot of strain on the mounting hardware putting it off-center like that, and 450lb/ft of torque is a lot of shearing force... Not that much difference in price between the two options, either.

But with adapters I effectively run a big spacer right? So say, for argument , there is a nice pair of forged 18x8.5 et 30 forged wheels out there ...15mm spacer/adapters would push those out too far right...

Correct, the spacers would effectively decrease the offset by the thickness of the spacer. You would effectively be running 18x8.5et15
