Al's shop does such great work!
Jett - what type of a resto are you doing? .... what is your goal?
.... Concours or Driver? .... Originality? .... Resto Mod?
Those 165/70R15 will give you a pretty big odometer error of 16% IIRC, so you'll add up "shadow" or "ghost mileage" post resto pretty quickly, & pay the ultimate value penalty for it later on down the road, as did other members on here. So you'll want to use one of the tire error calculators online to compare with the stock 165/80R15 size for error, to try to minimize it.
For example, Todd914 on here did a pristine CW refurb of a nice low mile original survivor red/black 73 2L & put the factory recco'd substitue 195/65R15s on with half your Pirelli's error at about 8%, & paid the penalty of a couple of $10Ks when he sold it after a short hold
Your wheels look to be dead on original correct - down to anodizing them & with the dulled down background.
So if you're looking for period correct - the 73-76 2.0's came with H speed rated tires in 165HR15 (i.e.: 165/80HR15 in today's /80 profile size), & you should stick with the 165HR15 (or at least a 165SR15 or TR, which weren't around back then) size tires.
Check at Lucas Tires in Long Beach CA & their UK counterpart Longstone Tyres for what they have (US can get anything on the UK site as well). You'll find that their tire prices are better than Coker in most cases, & Al could've had theirs mounted on his wheels for you, had you made the choice before he shipped them (for futre ref & for others reading here).
http://www.lucasclassictires.comhttp://www.longstonetyres.co.ukThere are also Universal & Coker to price check as well -
https://www.universaltire.comhttps://www.cokertire.comSome of the question is also what you want to drop $$s for a set of 5 tires, cuz they range from $70-100 each for basic B-brand 165/80SR15s, up to $400-500 for 185 XWX Michelins. Also, a member here has 2 unused/never mounted XWXs in the Parts FS classifieds for a reasonable price (for those), to get part way there.
Vredestein has a decent HR one at the lower end, & sometimes Bridgestone will have an SR or TR or HR rated 165/80R15, & there are some off-brand or B-brand 165/80R15's out there too, but I wouldn't recco any of them.
FYI - T speed rating is adequate for our 2Ls /4s but wasn't out back then, & HR was overkill beyond the rated 119 mph spec top speed of a 73-74 2L (I've had my stock 73 2L up to 126 though), so the HR goes with more cushion, whereas the SR is too low for a 2L, but was spec'd for the 1.7L & 1.8L with lower top speeds - but are usable in real world sub-100 mph use..
The next step up would be the period correct mfgrs. & both Pirelli Cinturato & Michelin have 165/80R15 in S, H, & V speed ratings: Michiliin in XZX SR, XAS HR (the XAS needs tubes), as well as the period option XWX 185/70VR15 (nominal <0.1% error IIRC).
Another option there is on a tire very much like the OE "Dog-bone tread" Dunlop SP57 165HR15's which were most often spec'd on our 2Ls, 194-6's & 911s of that day (the 185 XWX above being the optional upgrade), is the modern retro tire by Blockley here:
http://www.lucasclassictires.com/165VR15-B...Radial-504p.htmWhile those choices above will look most original & period correct on your resto, you won't be dinged at any of the local Region nor Zone PCA Concours for having non-original size &/or make tires (originality isn't judged here in our Zone 8, & AFAIK not in your Zone either), & may only run into it at a non-PCA Concours where they'd look for old school Michi or Pirelli etc., & maybe at the national PCA Parade Concours. that's my truth in advertizing bit on tires, but I do like the old school size & make look on a well restored or perserved survivor 914.
If you're looking for a driving tire & don't care about odometer error, then others on here are probably up to date on the current choices, but I would still suggest using the tire calculator to get the least speedo/odo error tires with the performance specs/profile for which you're looking.
Also beware that some of the wider tires will give you rub marks on the inner front wheelwells, &/or at the outer F &/or R fender lips, which would cause damage to your frest paint - so choose wisely & test them out on the lift with full lock turns L & R, & at the R fenders.
There is a Tires & Wheels nailed topic at the O&H Forum with a lot of info on tires too FYI.
Good Luck!
Tom
