EH2 or EH2+ aftermarket wheels (for RFT)?

paulboucher · 08-28-2012, 07:26 AM

Did anybody find some EH2 or EH2+ aftermarket wheels (for RFT)? I am considering buying winter RFTs for my 135i since some RFTs are not that much more expensive than non-RFT, however, BMW wheels are much more expensive than aftermarket wheels. Manufacturers strongly recommend EH2 or EH2+ rims for runflat tires since the extra hump inboard of the lip helps to retain the runflat tire when run at 0 psi.

I found one, the Rial (German wheel manufacturer) Salerno which is carried by Tirerack. Unfortunately for the BMW 135i, BMW recommends winter tire size of 205/50R17 which require a maximum rim size of 7,5 and they don't carry the Salerno 17x7.5, only the 17x8. Gill the 1series expert at Tirerack said that I couldn't order the 17x7.5 through them. Even if I went with a wider winter tire, e.g., 215/45R17 or 225/45R17 (which would not provide as good snow traction) the Salerno 17x8 has an offset of 29 which is too low for the 135i (minimum would be 40)..so I will continue to look for a while...and if I can't find one will default to non-RFT tires....(Note that the relatively good winter RFT tire that is only $50 more expensive than non-RFT is the Kumho KW17 (discountinued but still available))

I found out that Nokian indicates that standard rims can be used for their tires, so no need for EH2 wheels seemingly!

"What is the difference between Nokian Flat Run systems and those of other manufacturers?

Nokian Flat Run system tyres can be installed on conventional wheels, whereas the systems of other manufacturers mostly require a special type of wheel."
