    I just watch a YouTube video 800rwhp gt500 had r888r, nitto 555r and my et ss on his car. He said the r888r hooked much better and had less wheel hop. His opinion was the r888r where the best. I'm going to try the r888r.

    I don't track my car or run it at the strip. It's a weekend cruiser. With the change to e85 the stock rims and 275 nittos were getting dangerous as it would brakem lose whenever you touched the gas. Just want to be able to take down a stock hellcat when the opportunity arises and not run it off the road if I touch the gas.

    I drove it at 616rwhp for a few years before the e85 swap and boy did that awaken the 2.9.

    Wait till you see the rims I ordered

    Just my observations from my own personal experiences with a built up car and all the bells and whistles.

    The MT ET Streets were a phenomenal tire but unfortunately it was discontinued.

    The MT ET SS is an okay tire but not nearly as good.

    The R888R is an all-around great tire for dry paved asphalt roads. They do not perform well on polished concrete roads or wet surfaces. Best way to eliminate wheel hop is FTBR and double adjustable shocks.

    The M&H is a great tire and should be considered a better replacement for the ET Street.

    Neither the M&H or the MT tires are stable at high(er) or freeway speeds. With the low pressure and the soft sidewall, they are not designed for continuous driving at those same speeds. They are for sprinting, not a marathon.

    Vehicle mods, tire pressure, tire size, tire selection, suspension setup, etc. will play a huge factor in any setup.

    There is no magical formula or setup other than getting intimate with your car and figuring it out for your setup.

    Take notes, make subtle changes, take notes again, repeat...

    Are you guys talking about the MT bias ply or radial tire being unstable? I have the old style bias ply MT/ET street and it does feel a little wiggly at the top end.

    It doesn’t really matter much. The bias ply will feel looser but neither are designed for highway use. I’ve used both and with the air pressure you are running for traction in either, your not going to be nearly as stable as a street tire. Even if it’s “DOT”.

    No issues with highway driving or rain driving with Toyo TQ at 25psi. I do have Hoosier drag radials on a 15" rim for the track and have driven on them on the street. IMO the tire is too soft and the sidewall is too soft to do significant driving on them. They are very easy to puncture. I noticed just after a few days of street driving that there were light slashes on the tread on both tires. I've driven my TQs for 3 years and they still look perfect. A few years ago I tested the Hoosier Dr vs the Toyo TQ at the track. Both put down the same 60' of 1.63 at full weight making 452rwhp. I know that's significantly less power than what you're making. With 616 back then and now you're saying 700+, you should easily be able to walk a stock Hellcat.

    Agreed on the TQs I had those a few years back and they hook well, in fact i broke the ring gears and twisted the threads on my 28 spline axles, on my 2V Roush w/ 535hp.
    Does discount tire still sell them? Where are you guys purchasing your tires from any good deals?

    Always buy mine from Walmart or Amazon. I know, weird but both offer wholesale pricing 24/7 due to sales volume.

    Good info in this thread. I'm going to miss my ET Streets when they're gone! Leaning towards a pair of TQ's for their replacement when the time comes.

    Well I'd say having less sidewall with a 30's series doesn't help.

    What works for some, don't work for others.

    Absolutely! As long as we are comparing the same product.

    Don’t have any personal experience with drag radials but I’ve run the r888r for the past 2 years and will happily continue to do so. My car was semi-daily driven rain or shine and I never had a problem with them in the wet or at highway speeds. As far as dry traction goes they hook up just fine with a little heat in them and they’re a blast in the corners.

    The r888r is more of a road race tire and it has a stiff sidewall but the compound is very similar to, if not the same as some drag radials. The toyo tq IS a drag radial and has a softer sidewall than the r888r which would give you more flex and straight line traction at the cost of some cornering capability. From what I’ve read the tq seems to have a stiffer sidewall than most other drag radials which would give it a leg up in cornering and stability but I can’t personally confirm this.

    Before I went with the r888r I considered getting the tq due to the lower price but I decided I like canyon roads too much to give that up. Either one will be good for your purposes it just depends on if you’re willing to sacrifice a little cornering for a little more traction.

    What tread life are you getting out of them?

    Can’t give a definitive answer as I switched from 17” to 18” wheels during that time period and had to get new tires for them. I’m still running R888R’s on my new wheels but the car is no longer my daily so I can’t really observe their tread life. For what it’s worth the old set still has plenty of life on them after a year and a half’s worth of driving which for me would be about 2,000 miles.
