When you say the front and the rear are the same, do you mean the tire SIZES are the same, because I doubt they would be the same brand and model of tire? From your description the load rating isn't that different, but the speed rating is. I would be more concerned with having different grip levels front and rear. If you live in a warmer area that might not make much, if any difference in normal driving, but if you live in an area where it gets cold it could have an effect when it gets cold. One end could lose grip before the other end. A lot depends on how you typically drive too. If you drive gently overall, might nit make any difference. If you drive aggressively most of the time, you could notice the difference much more easily.

As long as the circumference of the tires on each AXLE are the same you will be fine. What you don't want to have is one tire on the rear be a larger circumference than the other one on the rear (or front). match up front to front and rear to rear. Still not a fan of mismatching tires of different speed ratings and brands. Also, not the best thing either to have one axle be very worn and the other be brand new. You could run into issues with much different grip levels. Probably not a big deal in the type of driving you typically do, but you never know when that one special instant could come up unexpectedly.

yea I always replace both left and right tires at the same time. I just went thru some stupid stuff that the previous owner left. Long story short, they put the right rear wheel on the front and right front on the rear. One of thise rims was cracked and my tire popped on the highway so I ordered a pair for the rear which was the front tire size(front wheel was mounted to the rear from previous owner) then i had to order another pair for the rear and couldn’t fine the same brand so that how i got different brands. Lol u guys probably stopped reading this post already but thabks for the help. I guess the guy at walmart was just lazy and didnt want to mount my tires
