Goodyear Eagle F1 GS-D3

or

Toyo T1R

???

 

Oh my god, how many times do you have to ask this kind of stuff? Don't pu55yfoot around, and get some Potenza S03's.

 

lol....I had S03's previously...the GS-D3's were on par dry traction wise and actually slightly better in the wet...the GS-D3's had a softer sidewall (ie. less steering sharpness/response), but had better breakaway characteristics...

so I know all about the S03's...they are slightly overrated for the price IMHO...

in either case, I started this thread to learn more about the new Toyo T1R and how it stacks up against the GS-D3 from other opinions and hopefully someone on the boards here that has had both...

I absolutely loved my GS-D3's...but now am wondering about these new Toyo's since there are no real substantial reviews on tire reseller websites yet about them....

 

S-03s are mad heavy...if u want to keep it light, get Toyo T1S....they are one of the lightest street tires on the market....the T1s is actually 5lbs lighter than the S-03 in comparaitive sizes...i know u auto-x michael....keeping things lightweight is a + for you...and many members on this forum praise the t1s for being a great traction tire..

I'd say check out the Toyo T1Rs....not totally sure if they still keep the lightweight/grippy characteristics of the T1S...but i'm sure they do....Toyo has been releasing many great quality tires in the past few yrs

 

well for autoX I use their RA-1's...(r compounds) and I love them so far...even though they are most likely heat cycled out by now...these tires would purely be for the street but that doesn't mean I would want anything less than spectacular especially after knowing what a maxima with r comps is like!!! you get spoiled real fast! in either case, I hear the biggest downfall of the T1S's were noise and a very soft sidewall...apparently this has been greatly addressed in the T1R according to the company that is...but I think the trade off was the weight of the tires went up...

now the other question becomes should I abandon the 235/40/18 size I have on my streets wheel/tire combo I have right now and go with 245/40/18's or should I stay with my current aforementioned size...

 

hey michael, i just went to edge racing and found out the T1R weighs exactly the same as the T1S...i'm not totally sure if this is a good source...but i believe its a good start....here is the link

you have 18x8 hp evos right? I wouldn't hesitate to go 245s over the 235s if I were u...they fit the 5th gen perfectly according to the tire calculator...speedo/odo will not be sacrificed...plus its still within spec (width wise)

 

for some reason I suspect that I actually have the 18x7.5's evo's (can't remember what the owner of my car before said they were)...which sux...b/c then it would make more sense to go with the 235's...however, as it's my street tire and the tread width according to the manufacturer is only .2in greater over the 235's...I think it wouldn't make much of a difference seeing as how this new T1R is supposed to have very stiff sidewalls anyway! in addition I will just run them at higher pressure to keep those sidewalls from flexing over...I need that extra footprint/traction to get off the line when and if I finally throw my S/C on...

toyo I hear for some reason actually runs smaller than their counterparts...even though you would think that it would be standardized due to exact measurements such as 235mm 245mm...but I have seen a thread on a forum somewhere and they were next to the same size ES100 and they were noticeably narrower which is odd...the T1S was used in that comparison...

the T1R is considerably heavier than the T1S according to toyo's website...in 24/40/18 flavor...the difference is 24 vs. 26lbs...and in 235/40/18 it's 22.9 vs. 24 lbs...

 

I'd go with the T1-R personally. I've had multiple sets of T1-S and loved them. T1-R is supposed to be superior to the T1-S. I've never heard anything bad about the GS-D3, but it does seem to be a more expensive tire.

 

That's only a 1-2lb difference... still lighter than most competitors in the same size. Your definition of "considerably" and mine must differ.

Tire section width is measured at some arbitrary location on the sidewall. It doesn't denote the tread width. Though you can get the actual tread width from manufacturer's websites.

Best price I've found on toyos is www.toyosforless.com

 

The Goodyears F1 DS-G3 is the way to go. My next choice would be BFG KDW2 over the S-03's any day. Cheaper and better. I've got Toyo T1-R's in the rear. They're decent. but not the best. Even my previous Dunlop Sport SP9000's were better.

 

Edge racing is wrong.

The correct links are:

http://www.toyo.com/tires/tire_specsheet.cfm?id=20 and
http://www.toyo.com/tires/tire_specsheet.cfm?id=2

 

The measurements are not exact. The first number in a _nominal_ tire size must end in a five. That means that a tire that -- on the _specified_ measuring rim, which is an _essential_ part of the measurement, because it will measure differently on a 6.5" wide rim than it will on a 7.5" wide rim -- measures 230.5mm will be specified as a 235, and a tire that measures 239.5mm also will be specified as a 235; a 240.5mm tire will be a 245 and a 249.5mm tire also will be a 245.

Similarly, nominal aspect ratios are specified in multiples of five, so, for instance, a 50-series tire may have an actual aspect ratio anywhere between 47.5 and 52.5.

 

All of the BFG tires are based on two decades old technology. Since Michelin bought the BFGoodrich brand 15 years or so ago, it has not used it for technological innovation, but rather as an economy brand.

If you want a very modern tire with the latest technology, you want a Dunlop SP Sport 01 or the radical Yokohama ADVAN Sport. Dunlop is where Goodyear -- which has owned Dunlop for a couple years now, after buying it from Sumitomo -- puts its newest innovations, which is why the SP Sport 01 is a more modern design than the Goodyear Eagle F1 D3. The Yokohama ADVAN Sport is the first tire affected by the next wave of revolution in tire design, nanotechnology. Through nanotechnology, the ADVAN Sport actually gets more tread on the pavement for a contact patch of given dimension without compromising the voids necessary for water drainage. The analogy would be to filling more of the seats of a given sports stadium, so while the size of the satdium stays the same, there are more people inside.

 

Did you copy that last part about the Advan Sport out of a brochure?

 

........ no.

 

Well you should be in advertising or marketing if you aren't already because it sounds like you did lol.

 

agreed

 

he sold me

 

I've had both the S and the R. The R's have a slightly modified tread pattern that reduces noise and tread squirm. No difference in traction that I can tell (wet or dry). I've ridden on 245's and 235's on 18's, and much prefer the 235's. The extra sidewall on the 245 reduces steering response some.

 

I tossed in a vote for the Goodyears only because I have them and love them. I haven't tried the Toyo's to give a fair comparison, but the Goodyears size 255/35 19's perform exceptionally well on my 2002. The dry grip is very good and the wet handling is also very good. There are not noisey and offer a nice level of road feel. The only drawback, if there is one, would be all the sand and stones that are kicked up into the wheel wells when traveling slow. Up here in the Northeast where winter sanding/salting is routine, and barely cleaned up, it gets picked up and tumbled around inside the wheel well. This does create more of an annoyance than anything.

 

MoCoMax...so you ran 235/40/18 T1-R's...and also 245/40/18 T1-R's? and the extra sidewall (even though it's marginal) on the 245/40 over the 235/40 was noticeable in steering response? did you try running higher pressures on the 245/40 to stiffen it up some? was the ride more comfortable with that extra sidewall? did you notice any total grip (either off the line or in a corner) difference between the two widths?

 

I ran the 245's (and 235's) on the T1-S's. The R's are brand new, and I can only vouch for the 235's. I would still be on the S's if I could have found replacements a couple of months ago, but the S is discontinued.

On the 245 S's, I can say this much: I was disappointed by the steering response and the feel of the tire "rolling over" in hard turns. I experimented with tire pressures a great deal, and wound up riding with the fronts considerably higher than I normally would to compensate (upwards of 44-45 lbs). When I trashed the 2 left-side tires on a crater, I decided to bite the bullet and replace them all, moving down to the 235. The difference in steering response and sidewall flex seemed very noticeable (obviously a subjective measurement), even riding at 37-38 lbs of pressure. The ride might be a little harsher, but didn't seem to be much different to me.

Keep in mind that these observations are all on an 8" wide wheel. If you went to 8 1/2", the 245's would probably be fine. On the 8", the 245's looked as if the tire was a little wider than the wheel, which made the sidewall 'bulge'. That might have had something to do with the sidewall performance.

I'm no tire "expert". All I can say is that I can push the car a lot harder on the 235's than I could on the 245's. The tires just don't wander around as much under hard turns.

 

so the 10mm extra width made no difference in the corners in absolute or the limit of adhesion? although the T1-R's have a much stiffer sidewall apparently so in the 245 size...they may be much better than the T1-S comparatively...

 

I've never been able to break the tires loose in the dry (except off the line or coming hard out of a corner), so I can't imagine the 245's would be a whole lot better. Now, if the sidewalls are a lot stiffer in the R, then going with a 245 might not give you the same issues I had with the S. You might have to be the test case
