I have a new set of run flats that came with the car when I bought it.. was looking at picking up at set of XXR 530s does anybody know if they are eh2 or eh2+
I contacted the company they said you can install run flats but I can't find anything documentation confirming this.. just looking for a second opinion

 

What size runflat tires do you have?

195/55-16 fits rims 5.5-7". Perfect for 6" wide rim
205/45-17 fits rims 6.5-7.5". perfect for 7" wide rim
205/40-18 fits rims 7-8". Perfect for 7.5" wide rim

XXR 530 come in many sizes to fit the MINI (4x100 bolt pattern) but offset needs to be not too aggressive

16x8 et20 - compared to OEM 16" wheel, this will be 9mm further from inner suspension and poke out 47mm more which is a lot.
The 16x8.25 et0 will poke out 70mm more than OEM.

17x7 et35 is fine with OEM 17" runflats
17x8.25 et25 will be 7mm further from inner suspension and poke out 39mm more
17x9.75 et25 will be 12mm closer to the inner suspension (will need a thin wheel spacer) and poke out 58mm more.

If you are asking if you can put on runflats for XXR rims then yes you can. If you are asking if you can put on 205/45-17 runflats on a 17x8.25" rim then it would be less than optimal (stretched tire fitment) and stress the sidewall more. Not a good idea and better to stretch fit a non runflat. You can check with your tire shop to see if they have done stretch fit with runflats. I haven't heard of anyone that did this.

Your other option is to sell the new runflats on craigslist then get tires that will fit the rims whether stretch fit or not.

 

Thanks for the reply minihune..
As far as fitment goes I know the size I want since I was given a set of brand new run flats when I purchased the vehicle I didn't want them to go to waste.
Tires size is 205/45/17... the wheels I was looking to purchase would be 7-7.5 in wide at the most with no more of an offset than +35
My main concern was more in regard if I was able to run those tires on those rims safely. Apparently from what I've been reading if a wheel does not have that eh2/eh2+ designations, it is not safe to install run flat tires because the tire could come off the wheel if you were to drive with 0 pressure due to the lack of that extra hump missing in the wheel design

 

Send your question to the wheel company and ask if they have that eh2+ designation (rather than the H2 designation).

Is it possible to fit a self-supporting run flat tyre on standard H2 rims? If so, will it still work as a run flat tyre and what are the implications?

Yes it is possible, although Pirelli strongly recommends that EH2 rims be used because they guarantee improved retention of the tyre bead down to zero inflation pressure. In the event of run flat operation at zero pressure with H2 rims, provided that a Pirelli self-supporting run flat tyre is used in conjunction with a Tyre Pressure Monitoring System (TPMS) or air pressure warning system, the tyre will maintain its run flat characteristics. A TPMS is absolutely necessary to alert the driver that the tyre has lost pressure.

 

That's exactly what I'm referring to I read the same thing on the MOMO website but when I called XXR all they said was; yes I was able to install run flats but had no idea what eh2 or eh2+ was.. I received the same response when I contacted Next Level as well.. I just find it odd that they don't seem to know the whole eh2 thing
