I originally bought xxr's for my car as an impulse buy. The stocks are SO UGLY! Had them for less than 6 months. Then I bought RPF1s.

I'm seeing lots of guys in the same boat and I'm one of them. I went with 17x8.25 XXR with 225/45 tires not long after purchase. the wheels are 20+lbs. Now this spring I am switching to 17x7.5 PF01 at 16lbs and going back to 215/45 tires. I honestly dont know if it was the weight or the tire specs but something didn't feel quite right.

I should be saving close to 6-8lbs a wheel since im getting lighter tires as well. Ill report back on the results.

Yeah, thanks for the input. I see I have two choices: I get much better tires for my current XXR's like MPSS's or I go with Enkei PF01's still in 18" but much lighter....Either way its costing me money but I didn't buy this car to be unhappy with handling..

I actually just put a set of 225/40/18 Pirelli P-Zero Nero's on yesterday, I'm running fairly heavy wheels (23.5 lbs) but I love the feel currently.

Better than stock?

I don't actually think it is the HTRZ III tires here. I think its a combination of the change in offset and move to heavier wheels with wider tires.


The HTRZ III is actually a pretty good tire, I've used it several times and have never thought the sidewall was soft.

I'm thinking about Enkei PF01 18x7.5 +38 with Pirellis. What do you think about that in improving my situation? the stock offset I believe is 48 so the farther you move from this the worse the feel will be? is 38 too far?

I dont think wheel weight is the issue here. I had an XXR527 18x8.75 on a scale and it was around 21.5 lbs. A similarly sized RPF1 (18x9.5) is listed as 18.5 lbs on tirerack. Majority of FT86 drivers wont be able to feel a 3lb difference driving around on the streets.

What sumitomos are you running? Ive also ran HTRZ3's in 18's. While relatively soft compared to better max performance tires like a Z2 or RS3, its still significantly more rigid than stock primacy's in 17's

After looking back at your concern, could it possibly be a wider tire which will track steer annoyingly with the grooves and curves in the road, giving you the impression that its wobbling around? Even the most garbage triangle tire would not have its sidewalls "wobble"

Reviews may be your best bet to figure out sidewall stiffness.

I run Bridgestone S-04's on my BRZ. The first time I had a set mounted, it took about 4 shops to find one that could actually mount them.

HTR A/S P02..... definitely not the same tire as the HTRZ III I think most of us were under the assumption you were running.

I actually found a review I did on the Z III. May be worth looking in to different tires, lol. The A/S is just a normal all season. I would put that on my beater car in a heartbeat, but not the BRZ.

It's been a while since I had stock tires on (had winter's on since November - actually they did the same thing that you are describing; a bit squirrelly at higher speeds, feel like your floating and don't have much control) so I can't really say for certain if its better than stock but I do feel like it is a lot tighter and I have more control - especially after running winters.

xxr are shitty wheels, but those all-season sumitomos are the real shitty problem you're experiencing. you can keep the xxr's and just upgrade to better tires, and that alone will make the driving experience way better (back to stock lol) again
