Time to upgrade to drag radials to keep up with motor build. Projecting 650rwhp. Going with JLP longbars. Nitto 555r's have been recommended more than once. Any other suggestions or recommendations are welcome.

I have 20 inch rims. I may get some 15s for the strip, but want the stock rim look for daily driving.

Nothing in 20" is going to hook 650 HP. Sorry. Big wheels are for show(if you like that look).

Mickey Thompson makes some 305/35R20, but they are $381 each.

M&H are overpriced although good tires. MT SR's are the best bang for the buck and wear well on the street/track. It's much safer to have traction available (except for rain) with DR's than to be skating around on regular street tires with that power level IMO.

But even these will not hook 650HP. The good 18" DRs are leaps and bounds better. Nitto. M+H. MT. A bit sketchy in heavy rain. But required for traction at that HP level.
Factory look? Why not stick with the actual 18" factory wheels then?

Nittos here and mine is driven daily and in the rain. They hook good wet or dry.

I run 18 inch L rims on my hd with MT drag radials all spring summer and fall it is the only way to hook on the street and that was at my old hp of 525 now at 700 I have no clue what to doo. I will tell you to give up on the stock HD 20 there is nothing you can do to hook up north of 500hp good luck with your build.

Ah! Never would have considered this as the thread is in the Gen2 Lightning Tech Forum. It is fine to post here per Site rules. But if you want accurate info from responses here it would be prudent to give this "minor" detail in advance. It will always be assumed to be a Lightning otherwise.
If you like the stock wheels you are not getting good traction. Sorry. There is no other answer. Your pewrformance wheelset can be purchased with stree/strip capabilities if you want. Or live with show on the streets and go at the track.

Sorry about that not so minor detail. That really was bone headed on my part.I find more people are in the L section and gives me a broader group to get feedback from. I am grateful for the forum and the resources that it has provided me with. Not to mention the friends that I am starting to make. I won't let it happen again.

you can post in the L section, there's more tech info/discussion here than the HD section, just post it's a HD in the first post so guys know for any of the things with slight differences, like DRs for OEM rims for 18 vs 20.
Now onto your question, you're getting all these replies of a 20" DR will never hook all that power....which is true it'll never dead hook that much on the street, but you know what, it'll hook a hell of a lot better than an all season tire! Night and day difference! It'll still spin and smoke and break loose, but you'll be able to give it a lot more throttle, and have a lot more traction available, than just having shit 420 treadwear all seasons on it!
The 20" Nitto DR is your best bet (I don't think it's a 555R though, it may be a NT05R, check their site, they only have 1 that'll fit right). Unfortunately it's going to wear out pretty quick with DD use. I'd expect around 5k miles on a pair (could be as little as 2, or as high as 8, but ballpark 5 till you see how much you're really going to be flogging vs just cruising). If it's a DD and that isn't really practical, then look for an all season tire with the lowest treadwear rating you can find. That'll be a softer tire for better traction. Not DR type traction, but better than regular all seasons, with better wear than a DR, but not as good of wear as a regular all season. It's a compromise you have to make. IIRC BFG KDW's are a 200ish treadwear rating which are probably the best hooking non-DR all season you'll find. Now if you go with a Toyo or Hankook all season, they're 420 treadwear, so they'll last a long time, but you'll be ice skating when you flog it.
I've ran Toyo's (420 wear) for years on the street, and the truck hasn't felt any faster at 800 rwhp than it did at 400 rwhp on the street, because anything over a light roll just lights the tires up. I'm finally just now 15 years into it converting to 15" rears for the street to run a 315/60/15 MT drag radial so I can enjoy tapping into some of my power on the street, but I will miss the HD look.
