Default Info On Kumho Ectsa R700 Rally Tires

Am looking for some tires well suited to general driving on dirt/gravel/sandy roads. Looks like the Kumho R700 is street legal. Thinking of using the 205-60-15's to replace the stock RE92 205-55-16's on an 01 Legacy Gt Wagon. Does anyone have any info,pros,cons on these tires?

They may be street legal but you definately don't want to drive them on the street. The compound is incredibly soft and they wear out extremely fast. I wouldn't recommend them for anything except dirt rallycross or use on muddy rally stages when wear isn't really any issue. I think that even most stage rallyists find them to not be durable enough and wear them out at an alarming rate.

My R700s have seen 3 rallycrosses on my Neon and are absolutely shredded. If I were you I would get some hard compound Michelin or Silverstones if you want real rally tires, or just get some Cooper Weathermaster ST that will be much more civil on the street.

For what it's worth, my R700's say "For Competition Use Only" on them... Dunno if cops read the fine print when they pull people over.

Supposedly that label is just so Kumho doesn't have to give you a UTQG rating.

They are a soft compound? My pirelli rally tires are like concrete... I couldn't see a rally tire being all that soft.

Most rally tires are of a very soft compound.
depends on which ones you purchase...

intermediates will last you a bit longer...
but are still realitively soft...

i'd even destroy them in a couple of stages

Ok, I have used R compound tires on the street , hoosiers , comp ta's kumho's. also michelin rally tires . and except for one flat on the hoosiers on the way home from an autocross never a problem.
these are not 50k tires, but if you are not sliding you car like you do in compition they will last a resonable amount of time , I used a set of michelin rally tires as daily drivers and "fun run" use for over 10k with out any issues and michelin rally tires are not DOT approved . I used the autocross tires in the summer months on the street too, my first concern was the first time it rained and standing water . I was suprised with how well they worked. But also I was ready at any time to switch back to "normal" tires owning a tire machine helps.
I guess what I'm saying is If you can afford them and keep an eye on them ( take them off of the car and look them over) give them a try

I too have run R compound tires on the street and the Kumho R700s are much softer......

To give you an idea......My friend mounted a brand new set for rallycross on his BMW 325e (less than 130hp). While we were getting lunch at the first rallycross he ran them at we made a 30 mile round trip on Tarmac at highway speed. This was no "spirited" driving at all.....By the time we got back the treadblocks were noticeably worn and actually peeling in some places. After 6 rally-x runs his treadblocks were already shredding......

Moral of the story: they will not hold up to even off pavement use, let alone any type of daily driving. Waste your money at your own risk!

The kuhmos the tire rack sells are VERY VERY soft. About half
that of a medium compound Michelin or Pirelli. Aparently we
can't get or they don't make any other compounds.
We've seen 1/2 the life of a 2x as expensive tire. Its been a
wash so far.

I prefer a medium compound for gravel and a soft only on
real mud or forest dirt/dust.

You might also check out Silverstone and Dunlop.
Or if SUPER cheap-o is your goal, look into the
rally re-treads. Some have gotten quite decent
over the years.

Sand really requires quite a different tire from gravel,

Default dirt gravel sandy use

Hi Mr Tom,
I used some woofed Kumhos on my wife's car during our blizzard season over the winter.
They held up ok on the street but had NO grip right off the driveway. I slid across the street into a curb one 15 degree morning and on my return, turned perfectly at double the speed. Aparently they warmed up in a couple blocks and held good afterward.
In mixed snow and pavement, they worked OK but as noted, spirited driving on pavement will screw up the edges in a couple corners.
These tires were already rounded and showed little difference after a couple months of daily driving.
We used the same brand all last year and at Rally NY after the pavement sections, I was surprised they didn't fare too badly in the wear dept. but are scary wiggly on pavement compared to Michelins.
If you really mean, sand, gravel and mud and don't need sharp edges, they grip good enough and clean themselves well. They are my choice for wet-mud over the Michelins.
