Need advice on Tire Sizes

[328ioc]

Hey guys I did some searching and found a lot about people who have different rims or people who want to to small/square on 135s but not much about bigger.

So here is my dilemma, I need new tires and my first option is the General GMax AS-03, but the rears seem to be back ordered (still waiting on final word from tire rack) and my second choice is the continental DWS.

If I cant get the 255's in the General should I just go with the continentals or should I try fitting a different size of the general out back? Say 265? I would rather go wider versus narrower.

Thanks for the help guys and if I missed a thread some where that can answer this please just point me there.

rear wheel size is what? 18x8.5?

With that being said, I wouldn't go 265. You'll have too much tire.

[328ioc]

Yeah stock wheels 18x8.5

Ok thanks, Ill spend a few more days trying to track down the Generals and if I dont find them I will go with the DWS's

Checked discount tire direct ?

[328ioc]

Yep. No joy. Only place I have see them is Tire Rack. My tire guy is who told me they were back ordered so he suggested I email TR and see if they have a set. So I am waiting to hear back.

The OEM is a 255/35... If you go with either the 245/35 or the 265/35, you'll be 1.10% different in overall size. Of course, the 245/35 will be smaller, so at an observed speed of 75 mph (speedo reading) your actual speed will be 74.2. With the larger 265/35, you'll be doing an actual 75.8 mph.

That being said, each size is really close. Personally, I went with 245/35 all around as I wanted a square setup and didn't want to try to fit anything bigger up front without having to do fender mods...

I don't think you would have any problem running the 265/35 out back. You're talking 10mm... Not that much...

[328ioc]

Yeah my only concern was rubbing anyway should have stated that. Plus our speedos are already off from the factory anyway.

[JupiterBMW]

Yeah..I was just throwing the numbers out for comparison's sake. The difference is so minute...

I am running on the zhp the dws from conti. They are a pretty good tire for an all season tire. However they are pricey.

Yeah they are a bit out out of my range but I hear good things.

Any one have any experience with the Yokohama Advin all seasons?

They look to be only about 30 bucks more for the set over the generals.

Are you not familiar with the atrocious ZHP rim offsets? You're not going to rub with 265's. But I wouldn't advise 265's anyways for bulge. Get 245's if you don't want the normal 255's.

255's are said to be the widest tires you can fit on an 8.5" rim..

Thanks I am now. lol

But it looks like Tire rack has them in stock so I should be able to get the 255's

Devlin,

I've been running Hankook Ventus V-12 EVOs on my ///M for the past two years and am now looking at replacing my rear sets. They have performed exceptionally well and I would use these again...

I checked pricing for these at discount tire direct and the front set 225/40s are currently at $147.00 ea.

the rear 255/35's are currently at $197.00 ea.

On a 8.5" 10mm makes a huge difference. When you get to that point, you need to factor in tire squirm as well as sidewall deflection.

There are multiple studies shown that trying to fit the biggest tire on a wheel results in less optimal performance. This is why I'm only running 265 when I can easily fit 275s

+1 on the V12s. I ran them on my E46 and will be running them soon on the M as DD tires.

[Mike V]

+1 on the V12 Evos. They are cheap and perform quite well, but are not for winter use. I don't see any reason to put no-seasons on your car anyway, unless you take road trips up north during the winter.

[328ioc]

I was going to go with the v12's as every one down here runs them but I do take occasional trips up north during the winter and the last time I did that on summers my E36 ended up on the side of 95 on a ditch because I had absolutely no traction.

This is really the only reason I want to go with all seasons.

Plus even though this is Florida I do still get freezing temps (I have seen it snow here) or at least very close to them on the rare occasion.

I'm getting new tires in the next week or so and I will probably go with the contour dws or Michelin pilot sports. Leaning towards the pilot sports right now because I live Michelin tires.


I have a question about rims though. I have stock 135 rims and continue tires on them now. Everyone here says that the zhp has a staggered setup and the rear rims are 18x5.

Tire rack doesn't recognize this when I look for tires. The option for oe tires says they fit on 18inch rims not 18x5. (in the rear).

I went outside to I investigate and measured both front and rear rims at 19.5 from top to bottom of rim. (not including the tire) obviously this isn't the proper way to measure rim size, but if the rears were in fact bigger, wouldn't the measurements differ?

The tires in the rear are obviously wider (you can an visually tell).

So I'm obviously missing something here.

Tire rack does have an option for the 330i with Performance package its in the drop down menu.

[LivesNearCostco]

Standard ZHP rims should be 18x8" in front and 18x8.5" in back. Measuring the externally visible lip of the rim would give you bigger numbers.

[nike001]

My Hankook's were/are alright. I get some tire pull and they're not as good as my old Pirelli's were.. but definitely adequate.

I aspire for some Michelin's all around next summer, as I already have a set of Michelin's out back since my rear Hankooks wore out faster than the fronts

You were running V12's in cold/snow?

I will be in the Philly area but Virginia is what boned me last time.

Oh hells no. I have a dedicated winter wheel/tire combo.

ok thank god lol I was gonna say you have some huge balls to do that lol.

I could have probably gotten away with it last year, but I doubt this year. My tires get real loud when it's cold and lose a lot of traction. I miss my summer ZHP wheels already :/

The compound isn't made to see temps below 50 degrees.

Yes I made sure to pick the performance package, not the sport package. Still says 18 all around.

[328ioc]

That's weird. I didn't notice a wheel size but it had correct tire sizes.

I believe you misunderstand what "staggered" means regarding our wheels; the wheels aren't different diameters, they are different widths (as you noticed). The front wheels are 18" in diameter & 8" in width; the rear wheels are 18" in diameter & 8.5" in width.

Yeah....in the Burgh...we call that a "stepped" setup. :)

Just to throw another tire in the mix I have heard some REALLY great reviews on the Bridgestone Potenza RE970AS's. Conti's are awesome for about 10k but then noisy and not quite right for the next 20-30k (depending how many miles you get out of them).

[danewilson77]

I have those....

Thank you for explaining this. I get it now.
