As the title says, would there be any big performance issues running standard load rear tires, Sumitomo htr-ziii 255/40/zr17s in the rear y rated are what I just mounted today

What I am planning on running are the same up front (My front just blew today), but in 205/50/zr17, but Sumitomo only sells this size in an extra load form, I was wondering if they would be much different if inflated at nearly the same pressure?

By the way, I was looking at buying them off of tire rack, as I have read reviews and they are an extremely good performance tire for the money.

Thanks!

Edit:
By the way these will be running on my 17" supercups

The XL tire in the front if it's a 205 is a good idea. The added construction will help to shore up the sidewall's stiffness compared to the larger rears. XL in front but not rear will be fine.

Please call me if you would like to order or use the link in my sig. Thanks.
