I'm looking at putting XLs on my truck and I hear you guys talk about how big a pain it is to remove the runflats. My question is; Do you have to remove them? Why do you remove them? Won't they fit over the stock rims? Is it just a weight and balancing issue? Sorry, that was four questions. I'm just trying to save time and money. The price goes up quite a bit on tires that already have the runflat removed.
