I have been offered a brand new set of HRE P40 Gloss Black wheels and Continental SP2 tyres from a reputable supplier here in the UK as follows:
19x9.0 Front mounted with 245/35-19 Continental SP2 tyres 19x10.5 Rear mounted with 295/30-19 Continental SP2 tyres and am unsure about the tyre quality, fit etc (would I get rubbing?). Any advice and opinions would be gratefully recieved. The wheels themselves are very light according tot he supplier. Price Ive been offered is £3500 for the whole package. The wheel...

I have been spending a lot of time on the HRE web-site, since they appear to be one of the few vendors who will supply after-market 18's, which is what I am considering for my sedan. I looked at these P 40's - they are sharp, but the HRE site says they are exclusively for Porsche. Are you certain they will fit? I would check with HRE directly rather than relying upon a local supplier's word...

Main question is 'are the tyres ok?' I dont really know continentals. Never had any.
Just had an email from them guaranteeing no rubbing.

Conti's usually aren't bad tires... Here's some feedback on the SportContact 2's: http://www.tirerack.com/tires/tires....SportContact+2
If you have a choice, the Michelin PS2's are a good tire (I've used them before) and seem to review better: http://www.tirerack.com/tires/tires....ilot+Sport+PS2 Hope that helps...

RAC is a much stronger wheel too.

Cheaper and stronger gets my vote!
And it's actually gonna be something like 6-7 K w/ tires For the thread creator: Wheels are ~ 21-22 lbs each. They are forged, but not die-forged. They are cut out of a piece of aluminum, not imprinted, and so they are slightly weaker than other better wheels. They are good, but quite overpriced. If you plan on tracking your car lightly, then these are fine. If you're looking into getting that design for your wheels (very nice IMO), I would suggest looking into something like Neez, which are stronger and about the same price. Better yet, RAC wheels will probably be stronger (and cheaper) than all the above, but are really not readily available. There is a thread that is alluding to potential development and group buy for the E92 M3, but this won't happen before 10+ months. If you're looking to get now, either get these, or Neez. Thread's here: http://m3forum.net/m3forum/showthread.php?t=204946 My 0.02$, but since this thread is about the tires and not the wheels, you may disregard my post. The tires should be good, but I know for a fact that the Michelin PS2 are LOVED by all that own them. Whether that's worth the extra 1K for them or not (I don't think so) is for you to decide. Good luck. |

Now back on topic...about the tires! Again, to reiterate, they are surely good, but the Michelin SP2 are better, but probably not work the extra 1K. |

RAC uses Champion, which outsource their forging to Japan, I believe.
BBS has given their information also Volk has various videos on the net showing manufacturing process. The 1st 2, you'll have to search around where they forge them, but you can find it. |

Funny thing is 8000TON is not even necessary to forge a automobile 19". 4000TON would do the job just as good. 8000TON is more for truck/bus wheels and larger applications. |

They have confirmed it. My knowledge of this is not high though, so I cannot tell you where this information can be obtained. If you do take time and search you will find it...I just don't have any!

HRE wheel construction
Quote:
"Everyone uses Closed Die Forging. Open Die or Hand Forging isn't accurate enough and is sort of the modern hammer and anvil. In terms of forging from a circle blank, I don't know anyone that does that as you would in fact not get much benefit from the forging process. The material has to flow and a lot of energy needs to be imparted into the material in order to change the crystalline structure. If you just pressed on something that was already near the final shape, you wouldn't gain much, but I don't really know of anyone that does this. In terms of 1-pc, the forgings start from bar stock as well and they are close die forged into a blank and then the barrel part is spun. The is the where the forged/spun term comes from. This method of spinning the rim from a forging is actually called flow-forming. In comparison, on 3-pc rims the barrels are spun from 5 mm thick sheet, not a solid. It is almost the same process and uses the same type of machine w/ a similar end result, but w/ 1pc, you have to go back and do a final machining pass. This does allow the 1pc to be extremely precise though if done properly. Crimsone90's post about these methods is accurate. His earlier post about HRE was not. He assumed we didn't do it the right way. I really don't know many that don't do it like this, maybe some of the cheaper guys, but not anyone that sources from APP or Japan."
