What slik tires use for drag?
 

Hi

I have a RX7 FC 13bts5, with 330/350RWHP. Whats the best size of slik tires to use on a drag day?

regards

26x8.5x15 would work well.

Please, can you explain me that size? I have 16''wheels.

regards

For 16" wheels you can go with 26 X 10.5 R16 tire. I use Mickey Thompson 255/50R16 ET Street Radial and I love them. I bought them a couple of years ago and I want to try there ET Streets now.


26" is the circumference, 10.5" wide, 16" wheel

Bringin this thread back.

This may seem like a dumb question, but for a 26x10.5x16, i would use a 16x10.5 wheel correct?

I guess my main question is, do you match the tire width with the rim width?

Not necessary.

Drag slicks/radials don't care as much as tires you are going to corner on when it comes to wheel width.
They have a soft sidewall and you will be running low psi so from a dig you will have about the same contact patch on a 7" wide wheel as a 10.5" wheel.

Ideally, you want a relaxed straight sidewall (no tension) for best sidewall flexibility on a drag tire, so I would avoid pinching or stretching the tire too much.

This is for a 15" or 16" tire in the 26" tall category. If you do some of those low profile 18" drag radials (don't) the tire would be more sensitive to wheel width.

Mickey Thompson ET street 26x10.5-16 shows a measured wheel width of 9" nominal size.

Like any tire try to match the tread width to the nominal wheel width. That size MT ET Street shows 8.4" tread width

I ran that size on 16x8 +30 on my FC and needed to roll the fenders a bit.

Would be perfect for a +40 offset wheel (FD wheel with 10mm spacer?).

You might find you have to air them way down below the recommended (20psi?) as the FC is a light car.
I ran mine at 12psi and they worked better off the line- though it becomes a balancing act on sapping power on the top end and how wobbly the car drives.

Very helpful. Thank you very much.

boas tambem tenho um rx7 de 1991 , um turbo II e estou a pensar por um garret gt35r , porque estou a reconstruir o motor e quero 350 whp pelo menos , tens algum conselho

No estoy.seguro que idiomas hablas pero entiendo.un poco. Haber si me entiendes.
Un motor s5 preparado bien con turbo gt35 hara 350hp con 15psi. Mas.o menos
Lo mas deficil es ponerle una computadora (microtech,motec,aem,power fc,haltech) y ponerle.su settings correcto para el motor y gasolina y tiempo ignicion. Despues nesecitas injectores y pumpa gasolina enormes. Primeros injectores por lo meno 720cc-1000cc injectores segundos por lo meno 1200cc-2000cc.

Umm seems like Portuguese , not spanish

Fixed.

Fixed.

sorry guys for writing in my native tongue , has some of you figured out i am portuguese, just like the guy who started this thread , i am rebuilding my engine and going gt35r .106 hotside , haltech ecu, 800-1600 injectors at least , front mount intercoller and custom exhaust , also porting the engine mild port or street port as some people say, any help and advise is welcome

thanks for being a good sport and not talking offence! they made jokes and i laughed. the world wins today.

Its all in good fun!

i can handle the jokes , the problem is that most people cant handle if you fire back at them and that´s not why i´m here i just need some advise on my build
