Spare Tire question- doesnt match our new TT tires

Hi All,
So I ordered 5 new tires online from Americas Tire ( Discount Tires) Carlisle ST205/75/R14 100M BSB load C - Had them shipped to the store and made an appt for yesterday to have all 5 mounted/balanced and put on our trailer before our trip next weekend. Somehow I guess they put our 5th tire on someones elses rig the day before so they did not have the tire to put on the spare. They ended up putting on a goodyear endurance which is the same size tire but a D rating. They didnt charge us for the upgraded tire nor did they charge us for the mounting/balance installation. My question is should I request that they order the tire I purchased and have the goodyear replaced with that? They offered to do this for us if we like. My concern is that it is a different rated tire and if we need to use it we would have a hard time finding a like for like tire for the Carlisle ST205/75/R14 100M BSB in the future.
I am not nuts about having a different brand/load rated tire for our spare even if it is a better tire.
Am I worrying over nothing?

    IMO you're worrying over the wrong issue as the Goodyear Endurance is superior to the Carlisle HD tires you ordered. A couple years ago one of the stock Chinese tires on my Coachmen split for no apparent reason and before ordering a new set of tires I compared the Endurance LR D to the same size Carlisle HD LR D. Putting my full weight on an unmounted Endurance the tire barely deflected at all, did the same with the Carlisle and it collapsed noticeably. Not saying the Carlisle HD isn't a decent tire, just that the Endurance which is manufactured in the US is demonstrably better.
  • The main concern I would have is the Endurance and the Carlisle the same physical size tire. They are both 205/75/R14, but sometimes different brand tires are sized slightly different.

    I'm not a tire expert, but I don't think different load range tires is a concern.
