265/35/20 front 295/30/20 rear for 666m

So was wondering if anyone tried 265/35/20 front 295/30/20 rear for 666m.

I know the 275/30/20 front and 295/30/20 rear 4s work but I want more sidewall in front. Front diameter goes up from 26.3 stock, 26.5 for 275/30 to 27.3 265/35 but we have big factory front wheel gap. Rear 295/30 is 27.0 diameter.

This is same tire size as 2018 E63S AMG. Think it will clear and give 666m a more substantial sidewall. Stock front is a rubber band.

This is the same setup I plan to run once the weather turns.

Yes this setup looks great OnPole! Definitely going same 295/30/20 pilot 4s rear.

Still considering 265/35/20 up front for .4Ē more sidewall. I donít think anyone has tried this size yet. Really think the front wheel will benefit from larger sidewall with these crappy nyc roads. Worried it may not clear shock perch or inner fender though.

BTW - what front lip is that OnPole?

I am thinking of going to 275/30 front and 295/30 in rear. Did you add any spacer, made any changes or just added wider tires to 20" Comp wheels?

Stock wheels and no spacers, just changed tires.

Cool. Thanks for update. Will be doing that after holidays.
Lastly, have you seen any changes with bigger tires?

He's not running a square setup - just beefed up the width of the tread on the from stock 265>275/285>295 - He's still running staggered.

265/35/20 front is too tall. Will rub. 265/30/20 front and 295/30/20 rear is better.

the 275/30 works, but will rub on the fenderliners at crank if the offset becomes too aggressive, especially if lowered

Iím not lowering and think 275/30/20 front, 295/30/20 is the best. So far the people in this forum running this size are having no problems. Most people are running Michelin 4s but I think some are also having luck with the conti etrme contract in this size as well.

Hi OP,

I'm also thinking about going 275/30/20 and 295/30/20 combo. Want to ask you some feedback about how good it feels. Any feedback will be appreciated, Thanks!

What kind of tires are you talking about? Just PS4/PSS but 35 diameter in the front?

I actually just put on 245/35/20 N0 porsche and 285/30/20 BMW star PSC2 and MDM is extremely intrusive on the track. Iím really regretting my decision...

You increased front diameter and didn't increase rear. If you want less intrusiveness try going to a 295/30/20 in the rear - it'll still be off compared to stock front to back ratio but it'll be slightly closer...

And MDM on the f8x is garbage.. it starts getting triggered on any banking turn without any loss of traction. so intrusive...

Thanks for the reply. How would a 295/30/20 be closer in diameter? Sorry for the noob question, I am bar for no expert in tires (In fact, i get a headache thinking about it. I just prefer BMW or a professional to recommend one for me).

I thought the diameter offset was 35 front and 30 rear, which means the rears are spinning faster than the front wheels. Whatís strange is, I actually think the car went from a very under steering feel to a very oversteering feel. Does this characteristic sound correct?

The aspect ratio (middle number) is a percentage / ratio of the first number. A 265/30/20 is roughly 1.9% smaller in diameter than a 245/35/20, therefore you threw off the stability control systems slightly, making the front to rear RPMs different. To keep the same stability control intervention as stock, you want to either reduce or increase the front / rear diameters similarly. Going to a 295/30/20 will increase diameter by 1%, so the front and rear will be closer to stock front and rear diameter differences.

Use the specs published on tirerack.com for your tires or use a tire calculator online to figure out the diameters. But long story short the only tire I'd run with a 245/35/20 Cup 2 like yours is the 295/30/20 cup 2. 305/30/20 would be even closer however but that tire is expensive and doesn't fit many setups.

Any major downsides to upsizing to a 275/295? Or should I stay with 265 F and run 295 R?
