Trouble mounting RE-71R on rear Nismo wheels

2011 Nismo#91 · 08-02-2019, 05:21 AM

Almost ever time (3 out of 4) I get new rears (302/30/19) on the Nismo rear wheels the last part of the tires bead will takes hours of work to get on the wheel. I've been to 3 different good installers and they all have a pain in the *** of a time to get these on. Does anyone have similar experiences or is something wrong with my wheels.

Yes they are very much pain in the *** to seal the bead. Had the same experience when mounting them on my nismo wheels.

Too small of an aspect ratio (the 30 in the tire size) that makes the sidewall very stiff. There is not a lot of "give" in the bead to allow the tire to be easily mounted.

A 305/30R19 isn't that much shorter than a 275/35R19 - about half an inch. It's probably just because the sidewalls on the RE71R are really, really stiff.

I use the soap/paste ar work on truck tires & even mounting low profile tires on the Z.
The make some more slippery stuff-but haven’t needed any yet.
295/30/19’s on 10” wheels & 325/30/19’s on 12” wheels
