265/30 R19 Tires

I went from worn Continental Sport Contact 6 to new Bridgestone Potenza Sport and felt the improvement in comfort as soon as I drove out of the garage. I also noticed the Bridgestone looked chunkier on the wheels. They run wider on the wheels which give better rim protection but if you're running a modified set-up, bear this in mind if you're already close to the arch. I went from Continental with no arch rubbing to the same size Bridgestone with very slight rubbing. I used RO1 (Audi Quattro) spec tires on my BMW and I later came across non-oe spec tires and could see the sidewalls on the non-oe were more rounded so maybe I should have used non-oe tires and would have got away with arch issues.
I also noticed the RO1 tires had less tread depth than the non-oe or other brands. The RO1 tires only came with 6mm new. Generally most brands come with around 7mm or more.
When I first put the tires on, I took it easy for the first 500 miles. At around 500 miles I started testing them and was disappointed. The traction control light came on unexpectedly and when I wanted to put some power down they'd wheel spin. The was at the end of Autumn and beginning of Winter so the temp was around 10 degrees celsius. It was at 750 miles when the tires transformed. Now they were great. Once they are warmed up they have no problem at 10c. Grip and handling is excellent even in the wet. But on lower temperatures around 3c they still lose traction plus if it's wet too then they feel unstable.
Bridgestone prices seem to be lower than other premium brands right now so my overall conclusion is try them if you're making a good saving. It's a decent tire. If you live in a warm climate they'll be superb but in the UK just take it easy during the colder months.
It's difficult for me to judge the wear as I've only done 6k miles on them and am now taking them off as I'm going back to Continental to stop the arch rubbing. The Bridgestone still have 4.5mm tread depth after 6k miles.

These tires when new had exceptional grip in the dry. Falcon XR6 turbo with 524 rear wheel hp barely spun. However they were so soft you could see little stones being picked up like the were slicks. They wore out within 6000km on the rear, but what do you expect with that much hp. The tires tram line and are not really comfortable. They weren't a bad drag tire but as an all rounder not really.

In my 25 years of driving, I've tried every premium brand and various UHP models within each brand. I've also tried a few mid-range brands. Continental still remains my first choice as it's the only brand that has consistently never lost traction be it dry/wet or hot/cold. I've used Sport Contact 2, 3 and 5P in the past. They never let me down. These SC6 were just as good and surprisingly much better on wear. All previous SC's had a high wear rate and would normally wear out around 10k miles. All other premium brands would last longer. But somehow I've managed to get 23k miles out of the SC6 and still have 2.5mm remaining so it seems I'll get a few more thousand miles out of them until they reach the legal limit. This is the most I've ever got out of any tire which baffles me as I wasn't expecting it.
Now that they are down to 2.5mm and Spring has started (UK), I can't comment on what they'd be like in Winter towards the end of their life but I suspect no summer tire would be so great. This Winter just finished they still performed excellent at around 3mm.
The SC6 (non OE spec) sit nicely on the wheel (265 tire on a 9j wheel). I don't like tires that curve in on the shoulders, I like them to sit flat and flush with the wheel for a more square look and these do that. The wheel protection isn't great but being low profile tires, it would be impossible not to destroy the wheel anyway.
I believe the SC6 is only available in rim sizes of 19 inch and above so it gives you a good feeling that you've got something that isn't available to everyone.
Going forward, if I was to buy any tire to replace these right now, I'd buy the newer SC7 to try out. It depends what you're looking for, I'm going by handling and grip performance. But if you're looking for the better value for money then there are other brands with good performance for example the Goodyear Eagle F1 (I've used Asymmetric 1, 2 and 3). Michelin, Bridgestone and Pirelli were also well balanced so from my experience you can't really go wrong with any premium brand if you drive according to the weather conditions. The only one I wouldn't buy again is Dunlop (I tried SportMaxx GT and RT) as they were terrible in the wet and cold.

These tires feel quite grippy around corners and sharper turns, even during rain it never felt like they were about to lose grip while driving around a bendy road. I have never tried them on gravel or any other unpaved road simply because the side wall is a little small and I don't want to get my rims scratched up. But other than that I like these tires, the road feedback is there, sometimes a little too much feedback depending on the road.

I have only 145 miles on these tires but I had comfort while driving and road noise was little to none.I pushed them to triple digits in the dry and wet and they felt solid.Other than a slight vibration which I suspect wheel balancing could be better, but the tires are decent for the price.

Not super grip from zero on fbo lexus isf

Look no further - so I went with the falken FK510s after extensive research into finding the ideal tire to replace the god awful run flats from factory - as the FK510s have a superior sidewall construction they provide the support of the run flats without the harsh, alloy cracking downfalls. In terms of grip, wet or dry, excellent, I was running in the 500bhp category and struggled to make the rear slip when new. Bad points - life expectancy isn't great, but not the tires fault, fronts will last for many many thousand miles but with my sprirted driving, the rears will last around 12 months with every day use, although fully legal tread, I did notice some slip starting to occur at about 60-75% through its life. With that said, I wouldn't buy any other tire for cars designed with run flats....

They perform great, the price is great. I have had 2 full sets of these tires now, my biggest issue? I have had 2 of these tires delaminate! Both on rear tires and over a year apart, 1 formed a huge bubble in the side wall and the side wall would deform dangerously under cornering, and 1 delaminated on the inner shoulder of the tire exposing cords and steel belt, the overall wear on that tire would never have suggested there was an issue. I really liked these tires, for years. But with these incidents I cannot justify buying them anymore

The traction is the benefit of this cheap tire. Very good choice. The problem is that the side are too soft!!!

I'm on my second set of these tires. I have a 550hp rwd car and as long as I drive normal, the tires perform well. Under little boost, the tires do break away in the rain and a bit more boost, the tires break away on dry road. They have also lasted a good length of time. I dont track or "spirit" drive with the tires. I have another set of wheels and tires I run for that. For my application, I got my bang for my buck.

Dry weather was decently grippy. Wet weather seemed fine as well but I didn’t really have a chance to really try the tires in the wet weather. Wear was shockingly fast. Bought a used car with these tires on. Had checked the tires thread wear beforehand. Was still meaty. After nearly 3 weeks of 50% city 50% spirited driving, was shocked to find the tires worn to the thread walls possibly due to my wheels not aligned properly/camber was not right. But 3 weeks worn out is too fast even with that reason. Distance covered is merely 1500kms at most.

These tires provide very little grip in both dry and wet. I have very little confidence in them as I have slid multiple times at very low speeds. The grip in wet weather is particularly bad. So much so that my DTC light occasional blinks when moving from a standstill. That being said, they have a fairly comfortable ride and aren't too noisy.
