I had 13x7s on my last TR7 and I am ready to do that again but in a year of looking I have seen nothing available. Everyone has gone to 15's. Can someone tell me what the weight of their tire and wheel is with the 15x7. I don't want to give up performance by getting bigger heavier wheels.

Check with Quiller Triumph in England. Here is a link to there Minilite replica wheels. They have 7j 13inch wheels. 389 pounds for 4 with caps, lugs and all!

I just got some Rota 15" wheels out of California. 15 x 7 and correct 3 3/4 four bolt spacing. They look like minilites. They sell on eBay.

I have at least 2 sets of 13X7 wheels. You can still get them thru Panasport, but they will cost you way more than $1000. Pretty sure you can get a set of Rota RBs in 13X7 as well. I have a set of 13X8 Rota RBs in a 4X100 bolt pattern that I use as autocross wheels on the BMW 2002, and the TR8 race car, however, its been years since I autocrossed either car. Back around 2000, the SCCA allowed pretty much every car that originally came with 13" wheels to move up to 15" wheels. That was the final nail in the coffin of the 13" wheel. Modern technology means you can find 15" wheels that are lighter than the 13" wheels that were available when they were popular. Add 15" tires, and that may or may not end up being a wash in the weight department. If you maintain stock bolt pattern, your cheapest easiest option is to go to 18racing.com(same guys on Ebay) and look at the Rota RBs. For a street car, definitely go 15X7s. The only reason I can see to stay with a 13X7 would be for autocross. The smaller wider tire you can fit on that rim means lighter weight, and a tire that will heat up faster. It will also offer a lower moment of inertia trying to get the car rolling. The 15" wheel and tire combo should have a slightly bigger contact patch than the 13X7. If you change the bolt pattern to 4X100, then there are a ton of wheel options. There are even several wheels in that size that come in under 10 pounds a wheel. Most spec racing series, like spec E30 and spec Miata, limit the lightness of the wheels to 13 pounds. That means there are a bunch of really stout wheels in 15X7 that weigh 13.1 pounds. 949UL, and Team Dynamic wheels are very popular and cheap in spec racing. Nice wheels at around $125 a piece. As always, a 7" wide wheel may or may not cause an interference issue with the fender lips. All depends on how well the panels lined up when the guys at the factory hit the button on the spot welder.

I have a set of original 13" alloy wheels. Maybe a few years of part time driving miles on them. Here is a photo. If interested, please PM me.
Thanks and good luck!

PS, sorry for my ignorance, but what is meant by 13x7?

Eric, it is the rim width, ie 7 inches wide x 13 inch diameter, the standard alloys are 5.5. No need to apologise, if we don't ask, we drift though life blissfully uneducated.

Charley -

I read that and thought "Damn, those wheels must be really heavy! Why would anyone buy those?" confused smiley

Then it dawned on me what kind of pounds you were talking about. LOL. I am so slow sometimes....

Wishing there was a way to put a pound sterling symbol in this board...
