Thoughts on tyre sizes

Hi guys,

I've bought a set of team dynamics 1.2 wheels in 7x13, do you think I will get away with running 185/60 tyres, much wider on the front and I think I will run into rubbing issues. On the rear I can fit 205's.

185/60/13 will be fine on 7" rims as will 205's. 6.5" might be more ideal but the 7" is within the recommended range. I'm running a set of the same without issue.

Also pay attention to tyre pressures - most recommend between 16-18 psi to achieve a balance of grip and ride quality. I know on my MK Indy I ended up around 16/17 psi on 15" rims and tyres, which gave a good balance. Harder than that made it slide around a little in the wet.

So these will fit over my Sierra hubs on my Indy then?

13" CATERHAM KIT CAR TEAM DYNAMICS PRO RACE 1.2 GLOSS BLACK ALLOY WHEELS

Thinking of running 205/60 13 as these will give me pretty close to the same diameter as 195/50 15

With the right offset yes. May also have to fit a shorter handbrake return spring (if rear discs).

Thanks Mate. Was going to go for ET35 which is the closest they appear to do to the ET40 sierra wheels I have.

I have drum rears at present, so I presume they will be OK ?

Would be handy to try one before I bought them, but I can't see that happeninng

as Nick said above about the tyre pressures I have 185 and 205 , 15's front and back and initially struggled to get "my head" round such a low tyre pressure so set them at 25 psi to start with and I felt every piece of grit and had a few exciting moments, so I bit the bullet and dropped to 18 all round and the difference was unbelievable, the handling is transformed she is not as skittish and feels really good, still have a bit of bump steer to sort out, and a lot comfier ride too
