Minimal tires for non-drag racing FI

[erikkire18]

maybe toyo 888R might be a good tire also, I skipped experimenting with tires and went to ET street R bias ply.

Happy with my MPSS/MP4S. Good traction in all conditions and I can go WOT in 3rd and at the very top of 2nd with some extra weight in the trunk. Always roll into it though, dropping the pedal will always end in a fishtail

It's more for Higher speed (140mph+) and track use on a 19 or 20" tire. Compound is very sticky, warms up quickly, and hooks from anything other than a dig in warmer temps. it's very expensive though. For just straight line and sub 140mph on the street ET's are the way to go.

I put Firestone firehawk Indy 500s 255/45/18 on my 18 x 8s and they hook up fine with almost 700 whp. Also less than $180 per tire.

They'll actually hook in first if you roll into it on a prepped surface with the tires warm.

Pretty savage tire tbh.

I'm running these Indy 500's
285 fr
325 r

Can't get it to spin in any gear at 400whp.

I feel that they stick better than MPSS.

Corners are unbelievable.

When I go FI, I will continue to keep the tires on.

Running NT555r's here with great results. Holding 2nd gear pulls mostly. Had Nitto G2's at first and they were useless.

G2s were an upgrade over the PP1 tires but agree 555rs give best of both worlds.

G2 on a summer day is the equivalent of driving in the snow on my car.

Agreed not even enough NA but just saying they hooked better than the pp1 tires.

Would NT05rs in 305 on an 11 inch 19 be enough for a whipple stage 2? I really wish they did them in wider sizes but no was a 345 is going to fit on SVE pp2 reps is it

I have nitto NT05 in 305s on a 19x11wheel on my car. Might as well be glass. Last trip to the track was terrible with all the spin through a soft launch in first, spun al, the way through second and a little wiggle in 3rd. Whipple stage 2 with a 3.6 pulley. Thinking of going MT SS on the next set of tires. Hesitant on running a DR on a stick vs a bias ply but don't want to give up street handling.

You'll have to roll into the throttle first and second... 3rd and on will dead hook

If you smash the throttle in 2nd you'll get a lot of spin at the top end of the rpm range... 3rd and on will be fine

Adding more width just changes the contact patch shape, it gets shorter and wider. Better compound is always the way to go unless you're just trying to look cool. MP4S work great for me, reality is you're not going to get a street tire to hook 1st and 2nd with boost.

Anyone have direct experience comparing the 555 g2 to the Indy 500’s?

Yup, that was my first set I tried after blowing through the stock Pirelli's. Tried the g2's and thought they were garbage too. Spun through 1st, 2nd and most of 3rd. Never really felt comfortable in those. Luckily I blew through the rears in 3100 miles so I was out of those quick. Indy's are head and shoulders above.

^ Agreed. From a tire perspective, to gain more straight line traction you either should get a stickier compound or lower the air pressure as that will truly increase the contact patch size. Wider tires aid in cornering grip since they horizontally elongate the contact patch (worst for straight line traction). I previously had an 07 GT500 with various upgrades pushing over 650rwhp and it would hook in 1st on the street with Mickey Thompson 275 width S/S tires. Those are one of the best street tires if you are primarily concerned with traction in my opinion.

The nt05r is much sticker than the vanilla nt05 isnt it?
