Downside to 305/30R20 on Rear Wheels

I just posted some photos for OP. I am running the 265's in the front with the 305 rears. As I said, wheels to change out to 9.5 and 11's. Rubber will switch over. Stock ride height for now. Probably would have saved a curb scrape or two if I had the wider tires on earlier.

Has anybody stuck with 255s in the front while going to 305s in the back? Is there any issue with that at all? I ask because it seems that everyone that goes up in size increased both front and rear by 10mm ending up with 265/35/20 front and 305/30/20 rears. I plan to go to DWS 06+ as most have. I live in MD and this is my only car so gotta think of winter. So is it possible and without issues to run a 255/35/20 front with 305/30/20 rear or would that cause some weird issues with wheel size/rotations?

I'm currently at the EOL for my Pzeros and want to try MP4S tires for a change this go around per a lot of members reviews. I am now deciding between 295 or 305 on stock rear wheels.
I've perused through the various tire size forums but I am wondering if anyone has any feedback regarding unintended consequences of increasing the rear tire size to 305. I like the look of the wider tires but want to know if there are any pitfalls. I'm not horribly concerned with grip difference as that discussion has been beaten to death in previous threads.
Does anyone have a picture with 305/30R20 tires on stock setup with jag's 20" rear wheels? I am wondering if tires will bow out and look funny over rim or if they look like stock tires. I saw a picture of a tire on one of the tire threads on this forum that looked like it was crammed on the wheel and about to explode but not sure which size it was from the description - definitely don't want that.
Any issues with speed/handling of car with wider tires? I ran the question by my local Jag service rep, as he is a good guy and I trust his judgement, and it doesn't look like there are any warranty issues or mechanical risks so long as the tires are the same diameter. Wouldn't a 305 be slightly larger in diameter with the same AR?
Hoping someone with experience with both tires could chime in and give quick pros/cons of each. The wider tires look nice but want to be sure there are no unintended consequences of sizing up.

Absolutely no issues

Agree....on tirerack.com note that they have a section width data point. For my UHPAS choice, the conti dws06plus in 305 was about the same as the michelin in 295 (a tiny bit larger) but weighed a lot less...so I went conti in 305. No regrets. My last Michelins were noisy....as3+'s fwiw. No issues with the 265/305 combo at all with conti dws06plus as the tire. Cannot speak to other tires but these are amazing.
