What is the best size tires for a Midget (mine is a '77) intended just for street use.

Prices are all over the place, any where from $26 each on up.

Thanks

SWA cars are more tire-width-sensitive than the 1972-74 RWA cars.

IMHO, 155/80R13 should fit no problem, and probably 165/70 if you can find them. 175/70 may or may not fit, 185/70 probably not.

Get the highest speed rating you can find, that will mean more of a handling tread, not so much an all-season tire with big gaps between the tread blocks.

Thanks Mike. Maybe these?

Don't forget......wheel size and offset , wire vs steel wheels, will come into play in making your selection.

155/70R13 is going to be much smaller than the tires that came originally on your car. 155/80R13 is what you want.

yawn, this topic comes up frequently enough it ought to be a sticky

Here is a list (attached below) from a catalog of the original 13" size, and closest alternative sizes (ignore the 14" portion which is for MGBs).

Also, here is a link to (one of the many) tire size estimators from the internet (google "tire size calculator"winking smiley:

I hope this helps, what I run on my Sprite Is 175/70/13! I like the larger size. Now the car has to be in alignment and I used poly urethane bushings, problem solved, car drives nice, better freeway cruising. By the way I've put over 30,000 of the car with the larger tires the rubbed until I redid the bushings.

Kumho Solus 155/80R13 is a fairly common choice, and aren't too expensive. TireRack

or if you want to get fancy grab some coker whitewalls... CokerTire

Thanks for all your reply's. I just got this thing back on four rather bad wheels and tires. Lot's of tread, but winter tires that must have been put on just before it was put away some 20 years ago, lot's of dry rot and they can't be trusted. They make great roll-a-rounds though while I do body work.

Forgot to mention the new tires will go on Minilites from Moss.

I've been driving my 62 Sprite with the same tires for more than 10 years and the PO must have had them for another 10 years. The treads look great but I'm concerned with rubber compound deterioration. I read that you can't simply go by tread appearance. I don't put many miles on the Sprite, but I do typically take the highway and travel at speeds in excess of 55 mph. Given the lack of safety features in these old cars, a tire blowout can be ugly.

Sorry for the long-winded intro to simply say I want to get new tires. I see several options, but i'd like to get a tire with a name on it that was around when the car was not considered a classic. The option I'm considering is the Coker Firestone F560 Radial Tire 145R13. At $70 each, they are in my price range.

I have original steel wheels and may consider minilte type wheels. I have two questions:

1. Is the F560 145R13 a good size for my original steel wheels? The chart posted by Ker suggest they are (if I'm reading correctly).
2. Any suggestions on minilte wheel size/offset to keep the original look and where to buy (OK , 3 questions).

Thanks!

That tire, Coker F560 145R13, should fit very well.

The width of the tire will be ever so slightly wider than original (original 5.20, Coker F560 145R13 says theirs is 5.40, or 0.2" wider).
The rolling diameter will be slightly smaller than original (original 22.5", Coker F560 145R13 says theirs is 22.29, or -0.21"winking smiley.

The slight width increase is inconsequential because the tire is designed to fit your stock 4" rim width (OK). The slight diameter reduction will be like a very slight rear end final gear ratio change (your engine will turn a little faster, and your speedometer will read a little slower). You can use a tire size calculator (google it) to do the math and tell you by how much, but it will be a small amount.
