Tire choices: Where have all the 245/45/16's gone?

So I've been looking around for tires and figured out the the 245/45/16 is nearly extinct. What I have found is that Khumo has two possible choices:

Victoracer V700
Competition Racing
Porsche 930 Sizes Available:
Fronts:225/50/16
Rear: 245/45/16 or 265/45/16

Kumho Tire USA, Inc.


Ecsta XS KU36
Extreme Performance
Porsche 930 Sizes Available:
Front: 225/50/16
Rear: 265/45/16

Kumho Tire USA, Inc.


The front standard size 205/55/16 is not available in either of these tire choices. A 225/50/16 is available and is .78 of an inch wider than a 205. The minimal extra width should not create a 'rubbing' problem for most cars except when they have been lowered. In which case the tires "may" rub on the inner fender and on the oil cooler shroud when turning. The diameter is the same.


The standard rear is available in the Victoracer and a 265 is available in both tire choices. The 245 is 24.7 inches in diameter and the 265 is 25.4 inches in diameter. This difference is approximately 3% which will (minimally) increase overall height of the car and gear ratio(s).


I will probably try a set of the Victoracer and am yet decided if I will go with 265 or 245...
Interested in comments /solutions from others who are still running 16" Fuchs

I run Fuzion ZRi tires in the stock sizes of 205/55/16 front and 245/45/16 rear.

They're good Ultra High Performance tires manufactured by Bridgestone. I've had them for about a thousand miles. Nice grip, not too noisy. Can't say how they wear.

I don't track my car, so that wasn't a consideration. Tire Rack has them for a good price, at least last time I checked.

Nice 930, by the way!

16s are getting rarer and rarer...good luck.

Fuzion is on one of my cars and it seems good so far. Another tire still offered in good size availability for your 930 that I have had ( and just bought another set ) is the ZR BF Goodrich G Force. Around $500 for all four. The are a great all around use tire.

Saaweeeeet Minerva! Damn I'm just sucker for that color.

anywho

Jah mon - I'm running the CUMho 225/265 16's on OE 7's/9's. LOVE THEM. They're a bit loud, but who cares in a 930? They grip like snot and look great - and are CHEAP!





Wear is pretty good, hard for me to opine after 2200turboPALOOZA miles on the brand new set (like dog years?), including entirely too many hotlaps (like 105*) @ Carolina Motorsports Park. But they seem to be wearing 'as expected' 8-)

The V700s are sweet, but I think they're a dedicated track tire than they are for a daily driver?

Sorry on the Fuzions Ray - my car came with them I couldn't wait to get them off. Cornering grip was surprisingly OK, they offered little to no warning on limit tho. The rears wore atrociously, and the 205s locked up hole puckeringly ALL THE TIME. Unacceptable. Course I drive w/ my hair on fire, whatever, but they just didn't do it for me.

Yes there is some gearing differential from my 205/245 Fuzions to the CUMho's. I put the Fuzions up to the mounted Kumho's and the (worn) tire only came to like the top of the new tire's script! Note it 'somewhat' off the line, but also gain it on the top end with some more cruising RPM's to play with.

no rub issues, slightly lowered in the front

YMMV, good luck!

I slammed into the 245/45/16 problem about a year-and-a-half ago and my guy at Tire Rack, who actually knows/likes our era Porsches (Troy, ext 339), talked me into trying a set of the Fuzion's...whomever mentioned that they're Bridgestone's is correct, and so was/is Tire Rack Troy (and everyone here who's chimed in to say the same) when he assured satisfaction; I've had a few sets on different cars, liked 'em when they were under my foster care, and the guys who've bought the cars have all since commented that they're happy with the performance, noise, and apparently decent wear.

For me as a dealer, they're a bit of a double-edged sword: nice that they're both good and cheap (less than $400 for all four!); annoying that I have to explain/defend them to some potential buyers...

Paul, I hadn't read your post when I posted mine...you're right, if you're gonna light your hair on fire on a regular basis (something I can't/won't/don't do with inventory cars), the Kumho's are the answer...

For me, when it comes to torched hair time, my personal 930 rolls on Toyo RA1's. I fell in love w/ them in vintage racing shaved to 4-5/32, and they kick royal azz on the street at full-depth - even in the rain...kind of.

Thanks for the kind comments about the car; it is Minerva, paint code 304-9-3
I ran into this problem when I needed to replace tires on my '72 911 that also runs the same size as the 930. I was running Conti Sports and was reasonably happy with performance and wear, with their higher price being the only downside. I accepted the Fusions as replacements as there were no other choices readily available (225's will not fit under the front of the '72). The '72 is light (appxly 2550#) But , for spirited Canyon carving and the ocassional track day the Fusions fail in performance miserably! In a word they pretty much suck! They are cheap though. They have about 2000 miles on them now and I will gladly throw them away if I can find a matched set of 205/55 & 245/55/16's !

The 930's can run the 225's under the front so I have more options; Victo Racer is a DOT tire with a strong bias to performance and will suffice just fine for 'in traffic' sessions between the spirited drives.
Voiture: I've run the G Force T/A before and was very happy with them;
I have not located a vendor that carries them? The BFG website only shows the R1 in 245/45/16's ?

Beautiful car!!! Both of them, actually.

Sumitomo makes the HTRz in 245/45/16. I have them and they are great tires for street driving. Grippy but wear pretty decent.

Wayne-
I could only find the 17" tires on Sumitomo website, so I phoned them to verify. Unfortunately they do not offer any tires in 245/45/16. Thanks for trying.

Toyo Proxes T1R they even come in 245/35/16.
i run the 245/45/ RA1's in the summer.
Yokohama has the ADVAN AO48. Also the ES100's i've had them and they were ok for me but others hate them for there noise and wear.

If you looking for an all season tire you need to step up to a 245/50, but in Florida why bother.

Thanks Emery! The Toyo RA-1 is a real option, as they do offer a street legal competition tire with some wet traction abilities. Probably most comparable to the Kumho Victoracer?

In my experience, RA-1's are night and day different/better/faster than Kumho Victoracer's...RA-1's are the closest usable DOT tire I've found to a Hoosier R6 in terms of grip, and the Toyo's are WAY better in the cold, wet, and wear departments than the nasty-fast, damn-near-slicks Hoosier's.

Going to revive this thread ...

My car is a bone stock '89 Turbo cab and I am interested in knowing what my 16" tire options are now that no one carries 245/45r16's anymore. The fronts are easy to find, but the rears are a real bugger. I am not interested in changing to 17" rims in case anyone is wondering (and my car is at the stock USA ride height).

Has anyone ever run 265/45r16's in the rear as the orignal post suggested? I am curious how they look (pics would be appreciated) and whether there are any issues with using that size. There seems to be plenty of Kumho Ecsta XS available. Thanks.

Bridgestone re11s are available in the 265 size from TR, they are a much better tire ESP for track work.

The only 265/45r16 tires I see on TireRack are from Kumho (2 choices) . . . at least that's what their website is showing.
