Isn't the FZ series a semi slick?

I'm interested to get semi's one day so an answer here would be helpful

The car I test drove the other day had semis on. I was amazed at the amount of grip! Only had a hint of wheel spin at full tilt in second gear!

Did a burn out with them and the second burnout I did when the tires were hot was very difficult! Tires was so sticky it was pushing the front wheels while my foot was flat on the brake with the rear wheels squirming for grip.

I give semi a thumbs up! But front tires I would say quality road tires!

when i went for a drive in RB25SX's RB30 s14 with semi's, when cold they still span abit, but then once warmer they got loads of grip.

265/40/18 cost R1800 max incl shipping each a while back .
just for referece a 265/40/18 road tyre cost was R4K min for a decent tyre

semi's in that size is a bargain

sorry for the hijack in advance

i'm also gona be looking for tyres soon, my wheels should come back from hi tech in a week or 2

can you use semi's for a dailly drive, how are they in the wet?
must you run semi's all round the car or can you just run them on the rear?

also howcome semi's are so much cheaper?

Do road tyres in the front and semis in the back.... best 50/50 option you have for the wet roads.

i dont really drive hard in the wet anyway with the sx tailhappyness (unless with then intention to slide) so do you think semi's could be fine for wet days with road fronts tyres? i dont HAVE to run semi's, but would like to

You will be fine in the wet with semi in the rear and roads in the front....

I certainly wouldn't mix road tyres and semi's on a car at the same time. The grip difference is so great that it will cause a huge handling imbalance. If you're at a point where you need semi's on the back, then you'll need them on the front as well, else you're gonna see your ass.

I've had and used the Toyo R888's on my Focus for trackdays, autocrosses, A1 Supercar Parade, and a fair bit of road driving. Their cost was about the same as a good road tyre.

The semi's actually grip pretty well in the wet due to the soft compound, the R888's are actually listed as a wet weather race tyre, however they don't have much of a tread pattern and so are more likely to aquaplane than a normal road tyre if you encounter heavy rain or standing water.

The other trade offs are that the semi's are a lot noisier than normal road tyres due to the open tread pattern and that they wear out a lot faster than normal tyres. They also pick up a lot of stones and crap off the road, and the soft rubber is more susceptible to cuts and damage by glass and sharp stones and such.
