I'm going to be bringing my 67 over to my house in the next month or two. The 45 year old tires on it held air 4 years ago, now? I need to at least have a roller to get it towed and into my garage. So if I now need new tires so be it. I'm for the foreseeable future going to keep the 4" rims. I want to be prepared if I need to get some new rubber pretty quick.

Research indicates I can get away with an 165mm tire on a 4" rim (stretching it, but apparently doable) I'm looking at 165/80r/14 and 165/75r/14 tires. The 165/80r/14 is within a 1/4 inch diameter of the factory tire. So I would think the speedo difference is probably about one mile an hour at 65 MPH. The 165/75r/14 tire would be about .85 of an inch shorter diameter that the original 5.60-14 factory tire and would be in the neighborhood of 3 MPH difference speedo vs. actual at about 65 MPH. I'm THINKING on a 4" rim rim with 165mm wide tires the slightly smaller side wall on the 165/75r/14 really doesn't amount to much in handling vs 165/80r/14?

I know Pirelli Centurato tires have have been recommended on the board in 165HR14. I have read some threads on MGB boards comparing the Centurato to the Vredestein Sprint Classic 165HR14. Dare I say it would appear the Vredestein tires were recommended a bit more. Not to mention about a $220 savings vs the Pirreli's for 4 tires. The UTQG of 220 isn't much to write about with the Vredestein's but I imagine that means softer compound and reasonable handling. I doubt I'd be driving more than 1,500 miles a year so they would still probably last ten years.

Thoughts, is the Vredestein's a reasonable choice? Is there anything else out there that should be considered in the $130 ea. price range?

Thanks

I bought these for my car over the winter. Haven’t put them on yet though so can’t give much of an opinion other than priced affordably.

I think if you are running the original rims yours are 4.5 width. That half inch makes a big difference. 175mm wide tires definitely won't mount on a 4 inch rim. 165mm is pushing it, actually the Vredestein's I mentioned may not be good for a 4" rim, I may need to go to 155mm tire, ugh!

Many of the early Porsche owners use the Vred’s with good results, albeit in a different size. They claim good handling and a classic look. Depends on what you want to achieve. If you just want something to roll on, than anything will do. If you want better handling and a classic look, then the Vred’s are about your cheapest choice for a good tire. Most likely your tires will age out (5 to 7 years) before they wear out. If you are a year or two from driving it than I would just buy some used tires.

Back in college, I had 185/65/14s on the 4" wide wheels...

Recommended size, or heavy Dorm drinking, Ramen budget size?

The Pirelli's 165hr14 have a recommended rim width of 4", 4.5" and 5.5". The Vredestein's are 4.5" to 5.5" I wonder if there is something in the Pirelli build quality that allows them to go down to a 4" rim, whereas Vredestein do not, hummmm???

Best bang for the buck I could find. Cheap, and the shop put them on. The car handled GREAT, at least until I overheated them one too many times...

If you want white walls I bought these. Not meant for high performance driving but I run them pretty good through the corners. I have them on four and half inch rims.

Uniroyal Tiger Paw AWP II , great tire really good price (especially at Walmart.com)

185/70/14 if you have the 4.5 rims and want to maintain the stock diameter
175/70/14 will work on 4" rims but is outside the recommended manufacturer width (4.5"-6")

these are touring tire with tall sidewalls so obviously they dont perform like performance tires , but good enough for lightly spirited driving

Wondering if there could be a situation were a Retailor would refuse to mount a Tire not in the recommended range?
