Tires Toyo or OEM Volkswagen

Not in my experience. I run 32/32 and my tires now have 35k on them, and are good for another 5k or so more no problemo. Wear is about as even as I've ever seen for a tire this far into its useful life. I messed around with a lot of different pressures before settling on this combo, and it's what works best for me.. and definitely no adverse wear issues.

I've run Toyo RA-1s and thought they did a fine job, although I never did better than 2.1. With more launches under my belt, my Dunlop SP8000s have performed as well.

some people don't like them but I get good results with my Toyo FZ4 205-50-15.

With regard to tire pressures, btw. I'm running T1-S in a 245/45 16 size on my S6 wagon, with 36 pounds of pressure in each tire. I started out at 34, and picked it up to 36.
