I have owned three different sets of HTR ZIII's. One set on my MS6 and now two sets on my VW. Both AWD, these tires are great for slow cars. The MS6 had way to much power for them in the corners, great on the highway and in rain, but heavy spirited driving.. no go. The VW however, my first set lasted about 60k. The second set that I'm on now is around 5k. If you are just daily these things than they might be ok for you. They are great in the rain and snow and dry (for a slow car mind you, at 3900lbs and 270whp/270flb I have had no major complaints).
Now, I have had some lateral grip issues with these tires on dry pavement. They really don't like to stick well during high lateral forces are put on them. Which in turn means be careful in the rain and snow when cornering. These are a great cheap tire if you baby the car. If you want something that the car is going to benefit from, you are going to want to spend a lot more money.
My recommendations if you want performance summer tires:
Dunlop ZII Star Spec are great, price isn't terrible but under 200.. barely. Great tires, but they dont last very long. I had 3 Sets of these on my MS3 and one on my MS6. GREAT TIRES, and for an Extreme Performance Summer tire, these do pretty well in the rain before they get eaten up.
Hankook RS-3 v2 A decent amount cheaper, also great tires, but they wont last long either. I had two sets of these on my MS3. I don't recommend driving crazy in the rain with these or aggressive on the road before they warm up, but once they are warm they will stick very well.
BFGoodrich G-Force Sport Comp-2 These are even cheaper than the Hankook's and have great ratings, I personally have never used these but have not heard anything negative about them.
Continental Extreme Contact DWS 06 Now these... these bad boys are a little bit more than the BFG's but cheaper than the other two. They are amazing all season tires and have been proven on the track. Great tread wear and life expectancy. If an All season is what you want with great performance, these are my highest recommendation.
All and all, the four tires here are great all around tires, and you have a decent range of price and performance here. So many options. But as
@Gandalf stated, if you can get your hands on a set of 17's, tires will be a little cheaper.
Good luck.
