Thumbs up Review - Sumitomo HTR Z III

I'm no tire guru but I thought I would post this up because there isn't a lot of information from Sumitomo HTR Z III users on NASIOC. Previous summer tires that I have used include: Bridgestone RE070 (on the STi), RE050A and Yokohama ES100's (on my old WRX). First off, I was looking for a good summer tire that wasn't noisy or expensive, I liked the RE070's that come stock on the STi, they handled amazing but had too much NVH (noise vibration harshness) - I don't compete in autox or track events so they were overkill for me.

After much debate and research I decided to go with the Sumitomo tire (I figured even if they were garbage, at least it was cheap, they are only $95 in 225/45/17!) They did great on tireracks tests (see below, they are up there with the Bridgestone RE050A pole position) and seemed to get good reviews on a few BMW and RX8 boards.

Now that I finally have them, I'm glad I choose them...they are obviously not the RE070s but the HTRZ are comfy, grippy and the price seals the deal. Ive put on about 3000 miles on the tires (went on a road trip to Oregon from CA) and I am extremely satisfied. I was able to drive them in pretty much all conditions, the freeway, city roads, crappy roads and LOTS of long twisty backroads at speeds of 20 - 120 (yes, sorry, speeding is bad, don't flame me Oregon had some killer roads) - There was also a hard downpour of rain I got to go through.

All the reviews and tests are pretty accurate, nice predictable turn in response and they hold on and inspire confidence around the corners. The only 'complaint' I have (and its not even an issue for me) is that the sidewalls aren't the stiffest at the limit (but not soft by any means) - but then again I probably shouldn't have pushed them so hard on public roads (sorry again!) I also think I could use a bit extra negative camber, I have -1 degree right now....considering -1.5.The only suspension mod I have are JDM pink springs.

Overall, I would definitely recommend these as a summer tire....compared to the other summers Ive used, I find these tires very similar to the RE05A that were on my old wrx wagon - the tread looks very similar as well. Oh yeah, thats the last thing I was going to mention, the tread is asymmetrical so you can rotate the tires side to side and back to back. Thats why I chose these over my second choice - the Falken FK452 (which is directional)....I also just wanted to give the HTRZ a shot and try something new.

For a spirited daily driver, you cant go wrong with these. Hope this helps.

Nice review. So HTR III > 050 > ES100 in terms of how you liked them?

Thats a tough call, I would rate them just about even with the RE050A. I had them on 16x7 RS wheels on my wagon had a lot of suspension mods (springs, struts, endlinks swaybar and steering rack bushings) so its not a perfect comparison (my STi only has springs)....I would say that they are very close. The RE050A might have stiffer sidewalls but then again it could have felt that way due to all those mods I had.

Both tires are much better than the ES100's - those things squealed around just about every corner that I pushed it on. Plus they tramlined on the freeway - tramlining sucks.

Damn, that sucks....I know what its like - when I bought the RE050A on my old wrx I ran over a nail a few days after installing them. Tirerack hooked me up with a replacement for good price though.

Asymmetrical means the tread pattern on the left half of the tire is not the same as the right half. They obviously are asymmetrical. There is an inside, and an outside portion of the tire tread, and have to be mounted properly on the rim, with the side labeled 'outside' on the outside .

What they are not is directional - where there is a right side tire and a left side tire. Tires that are directional can only be mounted on the side they are made for, where asymmetrical tires can be mounted on either side as long as they were properly mounted on the wheel.


Nice review though - surprising that a value price tire can compete that well with the other brands.

Not true. Only tires that are assymetric AND directional have Left and Right flavours.

Assymetric have outside and inside.
Directionals have rotation direction.
Assymetric and directional have both that is why there are left and right.

Looking at the tread pattern I don't see how they are not directional as well as asymmetric.

I have these on my Q45 in 245/40/18. No complaints so far, but I can't really judge the performance aspect in a 2 ton boat with 175K on the original suspension. I would say they are a liveable performance tire though - not too loud, no tramlining, decent wet performance.

Agreed that ES100's are not very good at anything.

yea, i have these on my car now and the drivers side tires look good, but the passenger side looks backwards. and all tires have the "outside" on the outsides. to me it looks like there should be different tires for the left and right. i almost want to remove them and install the passenger side tires the other way to match the drivers.

Any updates?

I'm in the market of new summer tires. Considering Dunlop Direzza Sport Z1 Star Spec, but it maybe overkill since I don't go to track nor AutoX... just daily driving.

I picked up a set of these recently, in 225/45-17, coming from 205/55-16

I'd say they are a very mature choice of summer tire. They are by no means the best summer tire around, however they are A:cheap and B: comfortable.


The sidewalls are soft-ish, but not so much that you notice under normal driving conditions. Only when you load them up do they roll a tiny bit. I've not got them to contact more than 1/8" or so past the outermost tread block, but they will move around on you. The upshot is that they a more comfortable than the stock re92A's i've been running.

They have plenty of grip for even the wildest evasive maneuvers, even if they don't quite make it as a racing tire.

The tire is fairly quiet, 'specially as i'm coming from the stock re92A's. Being able to rotate them side to side is a big plus in this department.


The way i look at it, these and the re760 sport's are the only two non-directional summer tires with a decent wear rating that tirerack sells, and the sumitomo's are much cheaper. They will take anything you could throw at them in a normal drive (without being an artard...), and don't sacrifice much in NVH or wear.

^^ Sniper has it right on the money - good post.

I've put almost 4K miles on mine (no track or racing) and I have been happy.

Just checked the prices. There is a 21% increase in price going from 215/45/17 to 22/45/17. That's outrageous! I think I'll stick with 215s like the door jam says. That or I will find another tire maker.
