You can get a 175/70 R20 tire from EzSpareWheel.com for $379 + $45 shipping. The wheel is designed to be mounted on vehicles with Brembo style calipers. I now have the 21 Prestige GV80. There is a storage compartment with a large plastic tray. THE TRAY HAS TO COME OUT IN ORDER TO SITUATE THE SPARE WHEEL/TIRE. With the tire mounted, there is about an inch space above where the floor panel is located. So, the tire takes up the cargo tray space. For me, I don't mind at all. I hope this helps.
Thank you for sharing the EzSpareWheel.com information. This sounds like a good (but pricey) solution to the no-spare problem.
The EZSpareWheel website makes clear that they promise that the spare will fit on the GV80 wheel but they do not know whether the spare will fit in the storage space. (See the specific website language below.**)
— Would you mind sharing a picture of the EZSpareWheel spare situated in your vehicle?
— Also, did you buy the changing kit with the jack and lug wrench, and does all of that fit in your GV80, too?
Thank you in advance for helping with the information.
