My 89 FJ62 has neither at the present time. It has 31's on 7" aluminum rims. The tires appear to fit inside the wheelwells, but some mud and dirt still finds its way onto the fenders. I'm planning to POR-15 the wheelwells sometime soon before any rust gets started there. My question is whether or not I should bother to replace the mudflaps that are missing from it, get fender flares or not bother and spend my money elsewhere. Thanks.
