I put a Continental 160-60-zr18 on my 87 750 and i love it. I cant get the outer edges to wear because the tire is too big for the rim but it sticks very well and looks good. I've had it leaned as far as my buds 929 and his brothers r1 so traction dosent seem to be a problem.
I was running the Dunlop K591's (110 front and a 140/70b18 62v rear)- the wheels on the RG are meant for radials. When I switched to the 17" wheels (Bridgestone BT20's) there was a short time that I was running the 17" rear and the front 18" had a Dunlop D205R Sportmax Touring 110/80ZR18. The bike didn't seem to squirm as much in corners with the radials. Dunlop discontinued the K591's and replaced them with (I think) a tire called the 501. I was running k591's on my GPZ550 (18"rear/19"front) and it did pretty well, but it was no gixxer.

I've got the same as You!!88' 4.5!!A 180 will fit!!!
I sent My rear wheel out to Kosman and they welded it up wider..to 5.5!!Now,My 180 looks like a 190!!
I was running 160/60 rear and 120/70 front Metzeler MEZ1's They were excellent but milage wasn't great. 3 rears and 2 fronts for one season. That's a lot of tires! I just put Bridgestone BT 020 's on they feel good we'll see how they last.
