I just spent the last few days figuring out everything I needed to get larger tires on my Grennie without a lift. There is such little information out there for 18" wheels, I thought I'd share what I found.
Knowing 285/75/17 size tires fit without rubbing, I needed to find what would be a similar size for 18" wheels. I used a tire size calculator to find 285/70/18 tires would be almost an exact size match.
So I order up my Falken Wildpeak RT01s. They fit just fine and look amazing.
Now comes the difficult part. The spare relocation bracket. I went with Agile's and they have the spacer available that isn't really explained well on the site what it's for, but you NEED it for the bigger tires on the 18" wheels. Without it, it hits not only the rear wiper, but also the door itself. The rectangular portion that is raised is not your friend here. So I put the spacer on and all seems well until I tried to move the rear wiper. It got stuck part way through it's arc. I think well I'll pull the fuse. The fuse also runs the front wipers per the chart in the owner's manual. So I just took the wiper arm off and tie wrapped the fluid hose and nozzle up around the bolt. Maybe not super clean, but who's going to see it behind the spare anyway? And is the rear wiper even necessary since you can't see out the rear window with the spare mounted?? I think not. Pretty disappointing that Ineos didn't think anyone would be putting bigger tires on a dedicated off road vehicle, but this seems to work for my 18" wheelie friends.
