Those are much thinner than stock (diameter).

Stock sizes are really good, it will be a lot stickier than stock with either of those tires in stock sizes assuming you can get them. If you're not going with wider rims, consider keeping 245/265.

well im doing this because im going to switch to apex rims. would like to put these on the stock 18's for a while and swap them to the arc8 when it arrives. what would be a reccomended tire size for me?

arc8's would be 18x10, 18x10.5

For 18" with larger rim width, 275/35 front, 285/35 or 295/35 rear

You will either need to compromise your current setup or compromise your later setup. Wheel width is very important to determining proper tire size. Why not just wait for the ARC8 to arrive and put on the right tire size for 18x10/10.5? (265/285 or something like that?)

well the arc 8 will come with R888 but im waiting on stoptech trophys so i can ship it all together. they will still take a long time to come and need one now as i destroyed the current set on track (as in wires all coming out)
