Will a rear 9.5 own wheel fit in the front?

Found a spare oem wheel. It's a rear. Wanted to see if it would fit in the front as a spare. (Used temporarily if a flat)

Haven't tried it myself, but even if it fits as it seems to, the rear wheel offset is very different from the front, so definitely drive carefully while you've got mismatched fronts.

Thanks guys. Just want a full size spare in case of long roadtrips to get home without getting towed.

sorry last question - will a 245/35/19 tire fit on this rim (9.5) wide? I have a spare I'd like to use if possible.

If the rim is a 19x9.5? Then "yes" that tire size will fit.

Was the 9.5 you had up front the factory rear wheel?
Thanks in advance

Fyi, Tire Rack has specs for their tires, one of which is "Recommended Wheel Width". I can't check right now but I believe 245 is ok -- but why would you want to mount a 245 tire onto a 9.5" wheel? Keep in mind that as width changes, rolling diameter also changes because tire height is always proportional to width, and obviously having one tire rotating faster than another one on the same axle could lead to problems. And even if you mounted a 245 tire to match the front tire size, it still wouldn't be right because a 245 tire when mounted on a 9.5" wheel isn't as tall as it is when mounted onto the stock 8.5" front wheel. However, a rolling diameter mismatch is probably a worse problem in the rear than in the front because a rear mismatch would create constant friction in the diff, so if you want to use a single OEM rear wheel as a universal spare, I'd put a 265 tire on it. At least that way you're safe if you need it on the rear axle, plus I'm betting 245 is about as small as you can go on a 9.5" wheel anyway.
