Tire Size Question

Hey Guys,
I am loooking at tire options for 22" rims. I decided on the Vredestein SUV Sessanta tires. Their tread pattern is killer!
Here is a shot of it...



They have two sizes in 22"...
295/30ZR22
265/35ZR22

I can't seem to find accurate OD's on these, so I resorted to math (which I know is not accurate).
The 295's calculate as 88.5mm tall sidewalls
The 265's calculate as 92.75mm tall sidewalls

My question is whether that is too big of a disparity to run the 265's on front and the 295's on the rear?
Also, if anyone knows the actual heights, please share!
Thanks!!

Based on a quick tire size calculator, the 295s would be approx 28.96" OD while the 265s would be approx 29.30" OD. One thing I would look for is a Revs-per-mile calculator and see if they are close, I would think they would be relatively close. It would be a difference of 8.5-8.6mm. Revs per mile 295-718 RPM 265-710 RPM

Edited above from a tire size calculator.
