Hello, I had new tyres of the brand Dunlop SP MaxxTT mounted on my G5. The older tyres of the brand Dunlop SP 9090 (225/45 R17 of course on the front axle. Unfortunately, I found the tyres on the front axle to run very restlessly, between 80 -120km/h easy vibrating in the steering wheel can be felt. Of course again to my tyre dealers of my trust. The tyres weighed again, while wur My tyre dealer said to me either to turn radio louder or to replace tyres. Now they may still have 60% and almost too bad to throw away. The tires were still bought in Dec. 2006, driven from spring 2007. Is there the possibility to step up to Dunlop and possibly to cut out a few new ones on Kulanz or negotiate a discount?
