No chance.It's gonna start! Run!
i have fitted my winter A/Ts now i will swap them in the summer and then do them ever 5k i was told buy the no more than 5mm is the tolarenceIf it was mine I'd swap then over asap - and in the future swap when the difference is 1mm.
I swap mine at no more than 5k when the difference is under 1mm
Should be no problem - but don't blame me if .......
According to what I've picked up over the years the difficulty is with folks putting brand new 8mm tread on the front and having only 2mm or 3mm depth on the rears.

Try the "Turnip Test" and measure the temp of yer vcu after a drive. If you int got a measuring thing, put yer hand on it and guess if it's cold, a bit warm, hot as a bath or just got back from the hospital burns unit. Problems may cause the vcu to work harder and get warmer.I asked this a while back , You won't get a clear answer

It’s difficult to know how much pressure you put on the wheel to turn the wheel yourself, compared to someone else trying theirs. Bit like the difficulty in describing how tight it feels on reverse full lock. The best thing to do is measure it and compare results with one of the tests.Going to buy one of them temp guns ( can they be used for the auto box oil temp too ? ) when I change that ?
Original 71,000 mile VCU with no problems or tightness , Can just about rotate one rear wheel by hand with wheel up . When I have felt the VCU it has been cool/lightly warm probably the same temp as the tyres ?
This is after a urban drive of 7 miles with mostly 30 limits & traffic lights etc , Have not checked it after a dual carriage way run at say 65mph what would I expect after that ( still cool I guess ) ?
