Tyre profile 30-35 ?

Post by Rwg » Mon May 15, 2023 9:33 pm

Hi Folk,
Just a question, my tyres are due to be replaced 275 30 20,
What difference would using 275 35 20 tyres mean, goodyear f1 - not run flat
Cheers
Paul

first off i would go for Conti Sport contact 7 which im running cant fault them or Michelin PS4s tyres the best on the market for our motors
but if you change the profile size this has an impact on your rolling circumference and will knock tour speedo out by about 4%
here a handy site for checking theis and off set if you ever change your alloyhttps://www.willtheyfit.com/index.php?width=275 ... offset2=26
2018 B9 RS4 Navarra Blue
2013 B8 RS4 Sepang Blue
2007 B7 RS4 Avant Sprint Blue
2001 B5 RS4 Nogaro Blue
1998 B5 S4 Avant Kingfisher Blue
1993 B4 S2 Avant laser Red

Wow,
What a Comprehensive reply, many many thanks.
All sounds OK to me as I have two sets of 20" oem wheels going to try the 35 profile as I see speedo error is showing less than actual reading so OK through cameras
Also no contact and I see as only difference is to arch gap 14mm approx, this might be a good option to try and see if any less harse on ride.
My other set of wheels are now needing tyres and thinking as you suggest Conti 7 or possibly michelin sport.
Once again cheers great attachment
Cheers
Paul
