Updated to new wheels and 295/70/18 tires. I believe my spare is 245/65/18.

That's a pretty big disparity between tires and spare (about 4" I think). Do I need to consider a cheap spare that is close to the same size, or am I good as is. The tire place is telling me I'm fine for short distances, but I'm not so sure.

If 95% of the time spent driving is around an area where there is a shop within a mile, than no.

Trust me it sucks when you have to try and keep up to 50mph on a off-sized tire (especially if it is front tire) on a highway or in bad weather

You probably could pick up a correct size used tire for under 30 bucks at a local (non franchise) dealer.

Why mess around with a spare? Get a quality plug kit and air pump. Fuggedaboutit. Plugging a tire is easier than changing one and your truck loses 80 lbs.

I’ve only ever had to change to my spare on my trucks or wranglers twice. Both times it was sidewall tear (road debris) and on a highway with zero berm and I had to get changed fast and get out of traffic. Good thing I had a spare each time.

Double check your spare and make sure you have a full size 18” spare wheel( check your build sheet as well). If so, grab a used 295/70 on eBay (unfortunately that size isn’t super cheap or common). The question is whether you will be able to fit it under there with the shields in place.

Getting a matching size means you don’t have to worry about immediately getting to a shop.

If my choice in wheels and tires wouldn’t have been so $$& I would have considered getting 5 (and rotating my spare in). When you have tire blowouts like I have (actual tears where the tire has to be replaced), having matching size is a real plus because you can drive on it for a bit while you’re getting a new tire.

Awsome. Build sheet says full size spare, and Ebay has a ton of single tires available in the right size. Only question, as you say, is whether it will fit with the shields.
