RE-11 and RE-71R

[GlazierGlaze]

Hello All -

Looking at moving from my stock PSS to some better rubber.

I'm wondering what the ideal RE-11 or RE-71R setup is for the stock 437M wheels. I have MS spacers 15mm on stockers with KW HAS. I'm not slammed but I'm low.

I want to go ideally to the 275/305 setup on RE-11s, but that is only available in a 30 series tire. Any concerns if I was to drop down to 30? Any suggestions?


EDIT: Thinking I might drop down and go to RE-11s with 275/30-19 and 305/30-19. Thoughts?

Specific to the RE71R's, general consensus on F/R setup on 437M's is 265/35 and 285/35. RE71R's don't come any wider than 285's. That sizing should also maintain the proper front/rear diameter bias to keep DSC intervention to a minimum.

I would go with M0 265/35/19 amg gts spec and the star spec 295/35/19 M5 spec.

The Michelin super sports are the best all around performance tire you can buy. They are the standard for other high performance tires in ride, dry weather performance and, wet weather.

The stock 437ms rear 10" wheel is too small for a 305/30/19 which is designed for a 11" wheel. The ideal tire size for a 10" wheel is 285/35/19. The front is also much too small for a 275 and biggest size that would work is a 265.

The reason why I recommend the above tire setup is that the 265 is designed for a 9" front wheel and the oversized 295 are designed to fit a 10" rear tire. Also the 295 has the same amount of tread as the 305/30/19 at 11.1" which is really what counts at the end of the day.

As mentioned above, 305 is not feasible on stock wheel sizes. You may need to dial in negative camber to avoid rubbing too, so there's that.

If you're sticking to stock wheels, I recommend 265/35/19 and 285/35/19. The sizes may sound unimpressive, but do remember that the MPSS runs small and that a 285 is actually 10mm or so wider than the MPSS equivalent, same applies to the 265 in regards to the RE-11 and RE-71R.

The RE-11 is a bit better for every day livability, but the RE-71R is more intense with better grip at the expense of tread life. I don't mind trading the latter, which is why I got a set of RE-71R's today in the sizes I've recommended. Grip should be pretty awesome after I get some miles on the tyres.

I also recommend the RE17R 265/35/19 front and 285/35/19 rears. Great tires. Way better than stock.

I have tried the 305/30/19s in the rear. They do fit fine on the 10" wide wheels, but the contact patch is no better because wheels are not wide enough. No reason to get unless going with wider wheel.

Good to know guys. Thanks for the input.

Going to grab the 265/285 setup.

Good choice you're gonna love the RE71R. Keep in mind that they are super sticky and as a result, they will kick up a lot more pebbles onto your rear fenders.

Hold on don't order them yet. I have tried many different tires, now have 25,000 miles on my 2016 M3 MT. The RE71R's are the greatest but I am running 265/35-19 front and 305/30-19 rears, on stock rims. No spacers, not lowered. The 305 fit perfectly on the 10" rims, I know what the charts say. If you want the best traction these tires can offer, go with the 305's. No problem with DSC, no rubbing and they look great. Check the pics. Love em

HOW MANY MILES ARE YOU GETTING OUT OF THEM?

[Harveyd396]

2,000 miles so far, still look like new. No track time, only city and hwy. Just slightly more noisy than pss or contis. I can spin them in 1st gear but not 2nd when no DSC. Corners like go cart. looks fantastic. I have traction control set on Euro MDM so as not to spin them in 1st gear. Pretty good in rain too. In general very happy.

Stock suspension?

That's a big tire on the stock rear wheel. Any photos showing the wheel and tire profile?

I'm not sure I'd be too keen about running a smaller circumference rear tire compared to the front given the stock FR/RR sizing. The 285/35 is bang on for front/rear size variance.

[AhsanU]

Drove about 30 miles today on the RE-71R, felt just like the MPSS, maybe a hair stiffer.

I'll have pictures of the 265/35 and 285/35 tomorrow, but I'm glad I didn't go for 305's as my wheels are aggressive and I don't think they would've fit!

Only if you ignore all the 2016 Reputable Independent side by side tests.

I was close to going with RE-11, prior to doing research and reading those tests.
RE-71 is in a different category.

You asked a few questions. I really feel that the 305/30-19 is the best size for the rears. Yes the front 265/35 are slightly taller by .1 in. After driving 2500 miles with this combination the DSC does not feel this difference. You cannot see the difference by eye. Also the 305/35's would be too tall and probably would rub on the fender. The speedo would be inaccurate and maybe you would feel a very slight slower acceleration. My suspension is stock. As you can see in the pic the tire sits very well on the wheel, no apparent bulge. Just very nice curb protection.
I put on 20,000 miles on a set of Contis 305/30-19 rear tires and had no problems other than lousy traction.

I am currently running a Set of the Re-71R on my 19" BBS E05 265/35/19 front and 305/30/19 in the rear and absolutely love the tires. Slightly louder than the Michelin but the grip on them is amazing

Thanks for the added info. I'm guessing at higher speeds, there would be DSC intervention. MDM-mode or having DSC off would likely deal with it though. It's unfortunate Bridgestone doesn't offer more size options in these tires.

Do you have a picture of the entire rear of your car showing the 305 goodness?

[Harveyd396]

Here's some new pics of the goodness. I now have 2800 miles on the RE71R's and they are the bomb. Been up to 150 mph, pushed some hard corners, I'm a ramp rat here in South Florida. The DSC does not intervene at all unless it has good reason to do so. Feels perfect.

Nice. Thanks for the pics.

Good to hear you've had no issues with DSC intervention or otherwise.

I have seen this tire size combo on stock wheels but with the Advan Neova AD08r tires and it looked factory good to me.

I think I'm going that route soon as my stock size RE-71r's are almost done and don't provide enough rear traction.
