Looking at a used set of 15" Musca's for my 90 240. Wondering if these would fit? 15x6.5 pattern 5x108 aluminum rims Would 205/50R15 fit these rims and work on a 240? Note my 240 is stock ride height and will be replacing struts very soon.

 

whats the offset of those rims ? ("ET")... if thats a wheel from a FWD Volvo, its got the wrong offset, and you'll need to use 20-25mm spacers or it will ride too far 'inboard' and mess up the caster/camber, make the steering horribly heavy or spastic.

I wouldn't put 50 series on a 240, it will ride harshly, the suspension just isn't modern enough for that.... the stock 185/70-14 for a 240 sedan matches the diameter of a 195/60-15 which is about as big a tire as I'd go. the late model 240 wagons came with 195/75-14, and would fit 205/65-15 reasonably well.

when you step into something like a 205/50-15, there's a pretty good chance that tire size has a much higher load rating, which means it was built for a heavier car... with the lighter car you could very well find lousy traction. I'd try to stay around 92-94 load factor for a wagon, and 87-89 for a sedan.
